Product 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
