QuesTek Innovations licensed the production and distribution of their Ferrium S53® alloy to Latrobe Specialty Steel. Ferrium S53® is a high-strength, high-toughness, corrosion-resistant alloy. More importantly, landing gears made of Ferrium S53® no longer need cadmium coating. QuesTek designed Ferrium S53® to meet the U.S. Air Force’s requirements for landing gears that eliminate the need for toxic cadmium coatings.
