Abstract:

Custom 455 is a commercially available proprietary alloy. It is a precipitation hardenable stainless stell that can be heat treated to a tensile strength of 260 ksi. The fatigue, and general corrosion properties are good and the resistance to stress corrosion in a 3-12 NaCl environment is excellent. The fracture toughness at a strength level of 240 ksi is 72 ksi square root of in.. The combination of excellent properties and low cost 1.05 per lb. makes this alloy attractive for structural applications. Author
