Product Description
S32652 UNS 654SMO Super Austenitic Stainless Steel Pipe 1.4652 X1CrNiMOCUN24-22-8
S32652 (UNS 654SMO) Super Austenitic Stainless Steel pipe 1.4652 / X1CrNiMOCUN24-22-8 conforms to ASTM A312 and ASTM A269 standards for superior performance in demanding applications.
Material Overview
654SMo (S32654, 1.4652) super austenitic stainless steel contains 23% nickel, 25% chromium and 7% molybdenum, providing significantly better corrosion resistance than ordinary austenitic steels. This material offers excellent local corrosion resistance with superior pitting and stress corrosion resistance under seawater, aeration, gaps, and low-speed erosion conditions, making it an ideal alternative to nickel-based alloys and titanium alloys.
