Recognizing the need for high-strength alloys with good corrosion resistance to atmospheric environments, and a martensitic age-hardenable stainless steel. This alloy is relatively soft and formable in the annealed condition. Asingle-step aging treatment develops exception-alloy high yield strength with good ductility and toughness.
This stainless can be machined in the annealed condition, and welded in much the same manner as other precipitation hardenable stainless steels. Because of its low work-hardening rate, it can be extensively cold formed. The dimensional change during hardening is only about -0.001 in/in, which permits close-tolerance finish machining in the annealed state.
Custom 455 stainless represents a significant advancement in the area of precipitation hardening stainless steels. It should be considered where simplicity of heat treatment, ease of fabrication, high strength and corrosion resistance are required in combination.
