CarTech 275 stainless is a premium melted, high-strength martensitic, precipitation-hardenable steel which provides good corrosion resistance to atmospheric environments. The alloy is a modification of CarTech Custom 465® stainless designed to provide higher strength and hardness. CarTech 275 stainless is particularly suited for strip applications; however, the alloy is also useful for components fabricated from wire and small-diameter [< 1.0" diameter (25 mm)] bar products.

While maximum strength and hardness are achieved in the H900 condition [i.e. aged at 900°F (482°C)], other combinations of strength, hardness, and ductility are possible employing aging temperatures up to 1100°F (593°C).
