Custom455 stainless steel is a martensitic age-hardening stainless steel that exhibits excellent yield strength, good toughness, excellent corrosion resistance, and hardness capability of approximately HRC 50 through a single-step aging process. This stainless steel is machinable in the annealed state and can be welded like other precipitation-hardened stainless steels. Due to its low working hardening rate, it can be widely cold formed and has little dimensional change during the hardening process, allowing for precision machining in the annealed state. It is an option worth considering when a combination of simple heat treatment, ease of processing, high strength and corrosion resistance is required.
