QuesTek’s high-strength, corrosion resistant steel “Ferrium S53®” receives approval of A and B basis minimums for inclusion in the aerospace industry’s MMPDS Handbook

May 09, 2008

Evanston, IL, May 9, 2008 – QuesTek Innovations LLC is pleased to announce that its patented high- strength, corrosion resistant alloy Ferrium S53 has received formal approval for inclusion in the aerospace industry’s Metallic Materials Properties Development & Standardization (MMPDS) Handbook. This follows the approval of an Aerospace Material Specification for S53 (AMS 5922) earlier this year. QuesTek designed Ferrium S53 to be a drop-in replacement for 300M steel, which is commonly used today in military and commercial aviation for landing gear components.

The Handbook minimums demonstrate that S53 matches the ultimate tensile strength of 300M. With vastly improved corrosion resistance compared to 300M, S53 will extend the life of landing gear components and should eliminate the need for toxic cadmium coatings. Coupled with the Aerospace Material Specification, engineers can now design components with S53 and procure material for use on flight critical components. The design allowables will first appear in published form in “MMPDS-05.”

This unique alloy was developed through the application of Materials by Design®, QuesTek’s computational materials systems-design methodology. Charles Kuehmann, QuesTek’s President and CEO, stated “Obtaining approval of MMPDS minimums is another significant milestone in the development of Ferrium S53. Industry approval for the design minimums signifies the alloy is now ready for use in numerous aerospace applications and provides designers validated properties to evaluate S53 in flight critical applications. QuesTek is working with the US Air Force to qualify various landing gear components and anticipates broad implementation of this new alloy.”

Carpenter Technology Corporation and Latrobe Specialty Steel produce and distribute Ferrium S53 under license from QuesTek. Commercial and test quantities of S53 (AMS 5922) are available from Carpenter today. Latrobe licensed the alloy in December 2007 and anticipates commercial availability later this year.
