Andritz received an order from Valin ArcelorMittal Automotive Steel Co. Ltd. of China to supply a galvanizing furnace for a new coating line that will produce third-generation advanced high-strength steel. The line will produce hot-dip galvanized or zinc-aluminum-magnesium-coated flat steel for the automotive industry. Start-up is scheduled for the end of 2022. Andritz’s scope of supply includes a direct-fired furnace (DFF) with pre-oxidation functions, high-temperature radiant tube (RT) annealing and soaking sections, advanced ultra-rapid cooling and partitioning sections, and after-pot cooling (APC) and post-treatment sections.

United States Steel Corp. acquired the flat-rolled sheet patents and trademarks of The NanoSteel Company Inc. as part of its ongoing commitment to offer a wide range of advanced high-strength steels (AHSS). The NanoSteel Company designed and developed patented proprietary alloys that derive exceptional mechanical properties from their nano-scale microstructure, which creates a combination of extreme strength with the enhanced formability normally found only in low-strength mild steels. The NanoSteel grades can be rolled thicker than other high-strength grades and are designed for automotive and heavy industrial applications where higher strength-to-weight ratios are essential.

Metallurgists are developing new steels to assist automotive engineers in designing better trucks, cars and SUVs.
