455 Stainless Steel

Stainless steel 455 is a martensitic, age-hardenable alloy yielding strength characteristics that are roughly 3 times the strength of standard 304 stainless. 445 resists staining in normal atmospheres and shows no corrosion in fresh water, good ductility and toughness. This alloy is extremely stable during heat-treating making it able to be machined to close tolerance prior to aging.
