“A new alloy is as good as titanium at a tenth of the cost” – Business Insider, 8 February 2015

South Korea-based scientist Dr. Hansoo Kim and his associates at the Pohang University of Science and Technology have created a new alloy by reconfiguring steel by a few nanometers, or billionths of a meter. Though the manipulation occurs on the smallest of scales, it creates an alloy that is as durable and light as titanium alloys but more economical.

Steel is continuously on the decline; now that President Obama has mandated that car fuel economies double by 2025, the US automotive industry has been working with big-name aluminum companies like Novelis and Alcoa to manufacture car parts. The aerospace industry is also experiencing the same push towards aluminum, since steel — although inexpensive and sturdy — remains a heavier metal. The percentage of steel made parts in cars has dropped from 68.1 percent in 1995 to 60.1 percent in 2011. Now that Ford is working on its new generation of all-aluminum F-150s, you can imagine that those numbers have dropped even further.

Dr. Kim took it upon himself to create a new alloy that still uses steel, but also employs a few other lighter metals. The combination he discovered to be the best is iron, aluminum, carbon, steel, and nickel. Without nickel, Kim found the alloy too fragile; however, adding the nickel allows for a reaction to occur between the nickel and aluminum to make new nanometers that bind more efficiently with the steel. The crystals that the nickel create prevent the alloy from fracturing.

The new alloy uses a combination of relatively cheap materials, which means it can still be cheap to purchase on an industrial scale. Fueled by global innovations, it’s only a question of how long before light metals like aluminum, magnesium, and now titanium will start  dominating as the material of choice for automobile production.

“Turkey’s Crisis Dents American Steel” – Wall Street Journal, 5 February 2014

Turkey is the world’s biggest scrap steel importer and a key consumer in the $20 billion US steel scrap industry. But Turkey’s current economic crisis is taking its toll on the US scrap steel industry, the country’s weak demand and declining currency making imports very costly.

The US is the number one exporter of iron and steel scrap, selling $10 billion per year, more than two times the amount Japan sells, second to the US. Turkey has been the number one importer of US scrap since 2008; the country’s steelmaking companies mainly use electric-arc furnaces to melt down the scrap imports. Turkey, in turn, sells to Iraq, Saudi Arabia and the United Arab Emirates, becoming the largest exporter to these countries.

In the first 11 months of 2013, Turkey’s imports dropped 18% to 4.9 million tons, a huge hit to the US scrap steel industry. Turkey is now importing more steel from Europe, and manufacturing steel products from semi-finished steel items purchased from Russia, instead of manufacturing steel from scrap.

East Coast scrap traders are more widely affected by Turkey’s decline, whereas West Coast traders chiefly export to Asia. While demand from Asian countries, such as China, is predicted to continue growing, there is a worry that the demand could dwindle as China has its first “scrap cycle,” a phrase applied to a young, industrialized country that begins producing its own scrap with recycled steel goods. China will remain an importer for now, but the question remains whether China, like the US, will also become a global exporter of steel scrap. The US steel scrap industry has a lot to lose.
