Alloy H-11 (DYNAFLEX VAC-ARC®) is a medium alloyed steel with a relatively low carbon content. H-11 has good toughness and deep hardens by air quench from heat treatment. H-11 ultra high strength grade makes it idea for structural applications such as aircraft landing gear. It resists softening at temperatures up to 1000 F while retaining good ductility and toughness even at strength levels on the order of 275 ksi.
