Custom 455

Custom 455* stainless is a martensitic age-hardenable double vacuum-melted stainless steel. This alloy is known for being soft and formable in the annealed condition. However single-step aging treatments result in exceptionally high yield strength along with good ductility and toughness. The Custom 455* grade should be considered for applications that require simplicity of heat treatment, ease of fabrication, high strength and corrosion resistance are needed in combination. Typical applications are architectural, Food processing and handling, heat exchangers and conveyors.
