HPM® 455 Heat Treatable Martensitic Stainless Steel

heat treatable martensitic Stainless Steel, corrosion resistance, strip

Description

HPM® 455 is a precipitation heat treatable martensitic Stainless Steel. The composition provides a good combination of corrosion resistance and heat treated strength favorable for fatigue applications. The material is well suited for demanding spring devices The alloy has reasonably good forming characteristics in the annealed temper considering that it has a hardness of RC30. A significant radius is useful when bending is necessary in a fabrication. Cold working prior to the precipitation hardening treatment can drive finish strength up to 270,000 PSI (0.2% offset yield strength). The alloy retains a good strength through 800°F (Approx. 70% of room temperature). Resistance to stress – corrosion cracking is optimized by heat treating at 950°F. The overall corrosion resistant to normal atmospheric is equal to SS 430 with no staining. The alloy can be welded by resistance and inert gas shielded techniques. It also is suitable for brazing using a flux when possible.
