QuesTek Innovations says its ultra high-strength, high-toughness FerriumM54 steel has been approved for inclusion in the aerospace industry’s Metallic Materials Properties Development & Standardization (MMPDS) Handbook. This marks QuesTek’s second fully-qualified alloy, following the 2008 MMPDS approval of its ultra high strength, high toughness, corrosion resistant Ferrium S53 alloy, which is being used without toxic…
High-strength alloy achieves specification
SAE International has issued Aerospace Material Specification 6516 for Ferrium M54, an ultra-high-strength, high-toughness steel that is also highly resistant to stress corrosion cracking. The material covers the procurement of bars, forgings, and forging stock of M54 as a double-vacuum-melted (i.e., VIM/VAR) aircraft-quality alloy, and defines chemistry, thermal processing, properties and other material requirements. And hey, if it works in aerospace it could work for wind too.
