High Corrosion Resistant Hot Rolled Stainless Steel Pipe S32654 / 654SMO Seamless Pipe

S32652 (UNS 654SMO) Super Austenitic Stainless Steel Pipe 1.4652 / X1CrNiMOCUN24-22-8

ASTM A312, ASTM A269, S32652 UNS 654SMO 1.4652 X1CrNiMOCUN24-22-8 Super Austenitic Stainless Steel Pipe and Tube

Material Description

654SMo (S32654, 1.4652) super austenitic stainless steel is a premium-grade material containing 23% nickel, 25% chromium, and 7% molybdenum, offering significantly superior corrosion resistance compared to standard austenitic steels.

This high-molybdenum steel presents manufacturing challenges during seamless pipe perforation due to its hard, sticky nature, which can lead to eccentricity or cracking. Our specialized center perforation process followed by cold rolling or cold drawing ensures high success rates and quality consistency.

654SMo demonstrates exceptional local corrosion resistance, including superior pitting and stress corrosion resistance in seawater, aeration, crevice, and low-speed erosion conditions. It serves as an effective alternative to nickel-based alloys and titanium alloys, outperforming 904L and 254SMO in both high-temperature and corrosion resistance applications.
