2018 saw the UK metals industry in apparent good health. The steel industry was buoyant, with UK players investing to upgrade their facilities and making overseas acquisitions. Lightweighting remained a key market driver for aluminium, particularly in the context of electric vehicles, and UK innovation and research were in demand from global organisations.

Director of trade body UK Steel Gareth Stace says: “I would like to think that there is optimism for the sector in the UK. The demand for steel is fairly stable in the UK and rising in the EU and at a global level. We in the UK have an opportunity to seize those markets and prosper so that we are not just surviving but are thriving in the future.”

But he says that steel producers in the UK pay over 50% more for their electricity than their French and German competitors; this amounts to £50 million a year in additional costs.

It had been hoped that the Government would take action following Professor Dieter Helm’s review of energy costs but, according to Stace: “Its response offered no immediate plan, no concrete proposals and no hope that any relief is on its way, amounting to little more than another vague statement of intent.”

Capacity and capability investments

Nevertheless, the UK steel industry has been making important long-term investments.
Liberty Steel is investing £15m at its Newport plant to try to increase its UK market share by displacing foreign imports of hot rolled coil used in construction, automotive and pipe manufacture. The plant doubled production to 370,000 in 2018 and is aiming for further growth in 2019. Foreign imports currently take around 50% of the domestic market.

The first phase includes advanced descaling equipment to further improve the surface quality of the product, along with additional automation to increase process efficiency.

Planning work and front-end engineering is also continuing at Newport for a much larger investment involving the installation of an electric arc furnace and casters for liquid steelmaking and slab production at the site.

Meanwhile, Tata Steel, still in the throes of getting its proposed merger with thyssenkrupp approved by the European Commission, demonstrated its commitment to continued manufacturing in the UK by starting work to extend the operational life of its Blast Furnace 5 in Port Talbot, Wales, by up to seven years.

British Steel, which was created in 2016 when Greybull Capital bought the Long Products Europe business of Tata Steel, is investing £50 million to upgrade its wire rod business.

Richard Sims, British Steel’s Managing Director for Wire Rod, said: “We’re investing in assets across British Steel as we look to grow in current markets and enter new ones. There are great opportunities to be had by expanding and improving our product range and our wire rod business is an excellent example.”

In 2017 British Steel purchased FN Steel, a premium wire rod business in the Netherlands with its own wire drawing facilities, and, says Sims, the two businesses are now fully integrated, entirely complementary and give an excellent platform for growth.
“That is why we’re investing with such confidence,” he says. “In Scunthorpe we manufacture steel through the basic oxygen steelmaking route, meaning we’ve a high-quality capability upstream supply. By continuing to make investments like this, and acquiring complementary businesses like FNsteel, we aim to become the steel supplier of choice for more businesses across the world.”

The new facility will allow for a wider range of sizes (up to 28mm) with tighter tolerances to be achieved, as well as allowing for improvements in surface condition and microstructural properties.

Innovative forming for car components

Downstream from primary metal manufacture, automotive component manufacturer Gestamp opened a new plant near Wolverhampton that will have one of the largest hot stamping lines in the world. It will produce high-strength steel parts for customers including JLR, Nissan-Renault, Volvo, Ford, BMW, Toyota and Honda.
The plant will also manufacture aluminium parts in an innovative transfer servo press, including battery boxes for electrical vehicles.

Gestamp sources said: “With this plant, Gestamp will take advantage of Gestamp UK know-how to develop high-tech technologies such as aluminium stamping and hot stamping for the cars of the future.” 

Gestamp is part of an Advanced Propulsion Centre funded project to validate the use of the Hot Quench Forming (HFQ) process for body-in-white and chassis applications. The process allows complex components to be formed from ultra-high-strength aluminium. This gives the opportunity to reduce part count, weight, costs and tooling investment.

Exclusive rights to HFQ are held by Coventry-based Impression Technologies, which two years ago opened an in-house production facility. It is now making around 25,000 parts a year for commercial customers and has just secured business that will probably take volumes to around 100,000 a year – but the company doesn’t see its future as a volume producer.
CEO Jonathan Watkins says: “Our model now is to use this facility as a showcase for the technology.

Our strategy is one of licensing the technology. “We are also creating a not-for-profit partner network to make HFQ, which is a new genre of metal forming, into a global standard – the Bluetooth of hot forming aluminium. So, wherever you buy it around the world it will be made to a common standard and will effectively perform in the same way. The mechanical, geometrical and microstructural properties will be the same.

“We are potentially working with over 20 OEMs on projects at different stages. These include a lot of electric vehicle projects – for things such as doors and closures and, increasingly, battery boxes.” He sees massive potential for HFQ, with a possible market of 30 to 40% of all vehicles by the mid-2020s from electrification as well as applications on premium cars and SUVs.
“We think that typically there would be around 10 to 15 parts on each car, which makes for a market opportunity of 5 million parts per year,” he says.

Metal matrix composite specialist Alvant
was selected for Safran’s ‘Large Landing
Gear of the Future’ project.

Another company making the most of the demand for strong, lightweight aluminium parts is Alvant, a specialist iwn aluminium matrix composites (AMC). The company was selected by Safran Landing Systems to participate in the £28m ‘Large Landing Gear of the Future’ R&D project and it is also working with Ford on hybrid-AMC components for high-performance production cars. 
Commercial Director Richard Thompson says we are entering a growth stage for new materials. “The main drivers are that as product developers strive to achieve some of these new product requirements, they are getting diminishing returns on the effort they put in from innovation with more traditional materials.”

In many cases the solution has been to turn to carbon or polymer-based composites, but although they offer light weight and high strength they do have limitations in terms of fatigue and damage tolerance and operating temperature.
Thompson says: “They are looking for a metallic solution to overcome some of these issues, and that is what we have been capitalising on – taking aluminium, which is a high-performance material in its own right, and reinforcing it with a secondary material.”

Historically, Alvant has focused on continuous fibres as a reinforcement but more recently has expanded its offering to include particle reinforced composites and syntactic foams – very low-density materials produced by dispersing hollow glass spheres in the matrix to create very small air pockets.

Alvant has also recently launched a new multiphase material with a long-fibre reinforced outer layer and a syntactic foam inner core.

“We can get the density down to 1.5g/ cm3, which is very close to magnesium and carbon composites, rather than 2.7g/ cm3 for solid aluminium. You also get a huge uplift in stiffness.” Thompson says that the big push will be for the electrification of automotive power trains. “We recently worked on the rotor of an automotive electric motor and were able to reduce the weight by 40%, while retaining the stiffness.

You are not only reducing the overall package weight, but because it is a rotating element you are also improving efficiency. By lightweighting a rotating component you can accelerate and decelerate and the whole parasitic loss in trying to spin a heavy mass is reduced.”

More materials innovation on the way

New high-performance steels to meet the needs of vehicle electrification and other future technologies could be developed up to 100 times faster using a method known as Rapid Alloy Prototyping.

New steels are being developed at Swansea
University that are strengthened by nano-level
structures that are the same length as a human
fingernail grows in 1 second

A new £7m virtual factory using the technology is being set up by Swansea University, in partnership with Tata Steel and WMG, at the University of Warwick.

Rapid Alloy Prototyping, which has been developed at the MACH1 labs at Swansea University and WMG’s Advanced Steel Research Centre combines physical testing and computational modelling to rapidly assess hundreds of small-scale samples for strength, electrical and mechanical properties, as well as durability and resistance to corrosion.
Only a few grams of a new alloy are needed. At Swansea, samples will be made using an induction melter under a controlled atmosphere, while WMG will use a four-power-feed ingot printer.

One area where Rapid Alloy Prototyping could be particularly important is in boosting steel’s environmental credentials. 
Professor Claire Davis from WMG explains: “We will be able to explore the opportunities for increasing steel scrap levels in new steel production by understanding the influence residual elements such as copper and tin have on the properties and processability. This will help inform decisions on scrap sorting, selection and the levels that can be tolerated in different products, which will all contribute to the circular economy in the UK.”

The new Advanced Metal Processing Centre at Brunel University

In June, the Brunel Centre for Advanced Solidification Technology (BCAST) opened the Advanced Metal Processing Centre (AMPC) that, together with its Advanced Metal Casting Centre (AMCC), which opened in April 2016, will demonstrate technologies developed in the laboratory at an industrial scale. This gives industrial partners the facilities to develop and trial innovative light alloys and components before full implementation. The two facilities also provide a route for delivering the fruits of the research carried out by the Future LiME Hub – a national centre of excellence in liquid metal engineering.

Dr Mark Jones, Manager of the LiME Hub, says: “We have mapped out our technology and we are aligning to exactly what industry is looking for – going from the car maker down the supply chain.” Areas covered include fundamental research, new alloy development and industrial applications. Recent work includes a project on carbon aluminium automotive hybrid structures (CAAHS) with Bentley Motor Company, Gordon Murray Design (GMD), Innoval Technology, and Constellium.

The outlook for steel

Looking ahead, Gareth Stace says one thing we need to monitor very closely is the continued increase of steel imports into the UK.

He adds that we are probably going to see even more because of the effect of Section 232 measures – President Trump’s tariffs on steel imports to the US.

“The real evidence is that we have seen the price of steel in the US rise to meet the 25% tariff. The anecdotal evidence is that at the moment customers are paying the tariff because US steel is the same price as imported steel. While this means that US steel companies are doing very well, the users are paying for it and this is making them less competitive.”

So at the moment steel isn’t being diverted from the US into other markets. In fact, it has become a more attractive market because the higher prices have allowed importers to improve their margins.

But, but in the longer term, US steel makers may bring more capacity online to take advantage of the price.
“I think that the short-term impact of Trump’s tariffs isn’t being felt by the steel sector in the UK and Europe, but it could easily, and quite predictably, start to impact us once sites in the US either increase capacity or bring new or mothballed sites into the market.”

He says that the UK still needs more investment to safeguard its position and more confidence. There are good omens though, and he praises the way new entrants to the market have re-energised the workforce and shown they are prepared to invest.
“It means that we can all think of steel in a different way in the UK. We can think of the future and not the past.”



British Steel has won a two-year extension to its supply contract with Network Rail that it will see it supply a further 4,000km of rail on top or the 9,000km supplied under the original 5-year contract. The order includes the supply of innovative new rail material including HP335 which cuts life cycle costs through reduced grinding frequency, reduced wear and extended rail life, and Zinoco, a corrosion protected rail designed for aggressive environments. It has also won major new orders from Infratil, the Belgian infrastructure company, and London Underground.


Constellium has set an R&D centre at Brunel University campus for its automotive industry activities. It will form, join and test prototype automotive components such as Crash Management Systems, body structure components and battery enclosures for electric and hybrid vehicles at the facilities. In 2016 it established a University Technology Centre at Brunel focused on aluminium alloy development.

Research commissioned by Wyelands Bank showed that reveals Pakistan, Turkey and India were the UK’s fastest growing export partners for iron and steel. Exports to these markets are expected to grow by 5.9%, 1.4% and 0.9% respectively in the years to 2021.  Iron and steel exports to these three markets were worth $1.4bn in 2017 and the projected growth could generate an extra $29m a year for the industry’s exports.
