Description
654SMO Forged Rings & Seamless Rolled Rings
UNS S32654, 1.4652, Alloy 654, 654 SMO
Material Specifications: UNS S32652 654SMO Super Austenitic Stainless Steel 1.4652 / X1CrNiMOCUN24-22-8
Product Overview
654SMO (S32654, 1.4652) is a super austenitic stainless steel containing 23% nickel, 25% chromium, and 7% molybdenum, offering significantly superior corrosion resistance compared to standard austenitic steels.
Material Advantages
  • Exceptional pitting and crevice corrosion resistance in harsh environments
  • Superior mechanical properties with high yield strength
  • Excellent processability and fabrication characteristics
  • Outperforms 904L and 254SMO in high temperature and corrosion resistance
  • Suitable alternative to nickel-based alloys and titanium alloys
Manufacturing Standards
Primary Standards: ASTM A312, ASTM A269
Additional Standards: ASTM B673, ASTM B674, ASTM B677, ASTM B675, ASTM B676, ASTM B690
