17-4 Stainless Steel Bar UNS S17400 (Grade 630)

17-4 stainless steel bar is one of the original precipitation hardened grades developed in the 50’s. Primarily comprised of 17% chromium, 4% nickel, 4% copper, with the balance being iron. Other characteristics include high strength, toughness, and quality mechanical properties at temperatures up to 600° F. Engineers and designers frequently choose Stainless Steel 17-4 PH due to its high strength and superior corrosion resistance when compared to many other stainless steels.

Aamor-Inox 17-4 material offers following benefits:

High Tensile Strength and Toughness
High Hardness upto 600? F (316?C)
Excellent Corrosion Resistance.

Aamor-Inox’s produces 17-4 materials to meet the following specification: AMS 5643R, DIN/EN 10088-3, AMS 5622, ASTM A564

Corrosion Resistance

Material withstands corrosion better than any other standard hardenable stainless steels
Stress corrosion cracking resistance is developed by age hardening at temperatures of 1025?F (552?C) and higher
Aamor-Inox’s 17-4 material has good resistance to sulfide stress cracking at Rockwell C 33 maximum hardness as per NACE MR-01-75
