QuesTek to Introduce New Nanostructured Stainless Steel at the ASM Aeromet 2003 Conference

May 07, 2003

Evanston, IL, May 7, 2003 –  Advanced Materials & Processes, in its May 2003 edition, formally announced in the following article, QuesTek’s new ultrahigh-strength structural stainless steel that was computationally designed to replace non-stainless 300M for use in landing gear and other aerospace components.

Ultrahigh-Strength Steel Offers High Corrosion Resistance

An ultrahigh-strength, corrosion resistant structural steel with mechanical properties equivalent to those of 300M will be discussed by Frode Stavehaug of QuesTek Innovations LLC, Evanston, IL, at the ASM Aeromat 2003 conference in Dayton, Ohio, June 9-12. In addition to high structural strength, the alloy has general corrosion resistance similar to that of PH 15-5. The presentation will cover mechanical properties, Charpy impact energy, fracture toughness, and stress-corrosion cracking.

The alloy was developed through the application of Materials by Design®, QuesTek’s computational materials systems-design method. One goal of the new alloy design was to eliminate the use of cadmium at rework, maintenance, and manufacturing facilities where ultrahigh-strength steels are applied in structures such as landing gear.

Material design strategies incorporated into the alloy will enable accelerated selection because of the inherent predictability of a designed alloy, control of property variation within expected process limits, and the modeling of process scale-up.

QuesTek Innovations LLC (www.questek.com) is a global leader in Integrated Computational Materials Engineering (ICME) technologies, serving government and industrial private sectors. Using its proprietary Materials by Design® methodology, QuesTek has rapidly developed breakthrough alloys (based on Fe, Cu, Al, Ti, Co, Mo, W systems), coatings, powders, and other materials that provide improved performance, reduced capital (as well as operating and maintenance costs) and provide competitive advantage. QuesTek has developed four steels that are being used in demanding aerospace and other applications, has a large portfolio of other materials nearing commercialization with more than 20 US patents awarded/pending and relevant international IP coverage.
