AL 15-7™  [Stainless Steel]

AL 15-7 is a semi-austentic precipitation hardenable stainless steel. It is used where high strength is required is required in the final form and formability is required during fabrication. The material is supplied in the austentic state where is can be formed into shape. Subsequently it is heat treated by a two step process to form a martensitic structure and precipitates. The material has a moderate level of corrosion resistance approaching that of Type 304 stainless steel. The market application for 15-7 includes spring type applications in aerospace and other industrial markets.
