Latrobe Specialty Steel (Now Carpenter Technology) Licenses Corrosion-Resistant Landing Gear Alloy

December 05, 2007

Evanston, IL, December 5, 2007 - QuesTek Innovations licensed the production and distribution of their Ferrium S53® alloy to Latrobe Specialty Steel (Now Carpenter Technology). Ferrium S53® is a high strength, high toughness, corrosion-resistant alloy. Most importantly, landing gears made of Ferrium S53 no longer need cadmium coating. “This gives our customers one more way to succeed by using engineered, vacuum remelted steels from Latrobe,” stated Hans J. Sack, President and CEO of Latrobe Specialty Steel.

QuesTek designed Ferrium S53® to meet the U.S. Air Force’s requirements for landing gears that eliminate the need for toxic cadmium coatings. Dr. Charles Kuehmann, President and CEO of QuesTek said, “Ferrium S53® significantly benefits the environment as well as the reliability of commercial and military aircraft. With their capabilities and experience in aerospace, Latrobe will expand Ferrium S53® penetration of the market.”

Latrobe Specialty Steel’s metallurgical and aerospace engineers foresee many other defense and aerospace applications beyond landing gears for Ferrium S53®. Latrobe will bring many new high performance materials to the market in the coming years. “Our cooperation with QuesTek helps Latrobe Specialty Steel to commercialize materials sooner. That means our customers can offer innovative products faster,” explained Latrobe’s Director of Technology and Quality Systems, Scott Balliett.
