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
