While cruising for Charpy data I found the following comment from a British steel concern:
Aerospace Engineering Steels for Airframes
The greatest concentration of aircraft steel is in landing gear components where strength and impact toughness are essential, where integrity is crucial. In modern efficient braking systems, the heat generated in emergency situations such as an aborted take-off, can take components to temperatures as high as 550° C - temperatures that can cause softening in traditional high strength landing gear steels.
British Steel Engineering Steels is involved in the development of products with improved temper resistance properties.
Corrosion resistance is essential in all airframe components exposed to the elements. As cadmium plating falls from favour, alternative solutions have to be found.
The Ultimate Solution?
The Holy Grail would be a stainless steel that could match the high strength and toughness of current alloy steels, as well as withstand intense local corrosion.
While the industry recognises that this is virtually unattainable, British Steel Engineering Steels is working with some of the world's leading airframe manufactures to achieve the best compromise solution.
