Description
654SMO Super Austenitic Stainless Steel Products
UNS S32654, 1.4652, Alloy 654, 654 SMO - Forged Rings, Round Bars, and Seamless Rolled Rings
Material Overview
32652 UNS 654SMO Super Austenitic Stainless Steel 1.4652 X1CrNiMOCUN24-22-8 is a premium super austenitic stainless steel containing 23% nickel, 25% chromium, and 7% molybdenum, offering superior corrosion resistance compared to standard austenitic steels.
Key Manufacturing Advantage
Our specialized manufacturing process involves center perforation of round steel followed by piercing, then cold rolling or cold drawing. This method ensures high success rates despite the material's challenging processing characteristics.
Performance Advantages
  • Exceptional pitting and crevice corrosion resistance in harsh environments
  • Superior mechanical properties with high yield strength
  • Excellent processability and workability
  • Outperforms 904L and 254SMO in high temperature and corrosion resistance
  • Ideal alternative to nickel-based alloys and titanium alloys
