Stainless Steel Grade Custom 455 | UNS# S45500 is an advanced martensitic alloy included in the precipitation hardening stainless steels. Combining corrosion resistance, hardenability, ease of fabrication, and yield strength that is 3 times the strength of grade 304. Custom 455 is known for being soft and formable in the annealed condition, but single-step aging treatments result in an exceptionally high yield strength that also demonstrates good ductility and toughness. Applications generally include heat exchangers, conveyors, food processing and similar industries.
