We supply premium-grade Hastelloy C-22 processed via advanced dual Vacuum Induction Melting + Electroslag Remelting (VIM+ESR) to guarantee ultra-low Carbon and Silicon content. Our comprehensive portfolio includes Sheets/Plates, Precision Round Bars, Seamless Pipes/Tubes, and Forged Flanges/Fittings. Fully compliant with ASTM B575/B574/B622, C-22 offers vastly superior overall corrosion resistance compared to C-276, particularly against pitting, crevice corrosion, and intergranular attack in welding heat-affected zones.
Our Service: Engineered for global B2B industrial infrastructure while offering "No MOQ for In-Stock Specs." We rapidly dispatch urgent custom small-batch orders alongside volume contractual supplies at factory-direct pricing.

Why Engineers & Buyers Choose Us

100% Traceable High-Purity Chemistry: Zero recycling scrap allowed. Our C-22 maintains perfect chemical balance (22% Cr, 13% Mo, 3% W) preventing premature equipment perforation. Every delivery features a permanent stamped Heat Number matched to an original EN 10204 3.1 MTC.
Optimized for Welding Integrity: Advanced grain-boundary control resists the formation of grain-boundary precipitates in the weld heat-affected zone, making it safe for immediate as-welded chemical vessel fabrication without post-weld annealing.
Comprehensive NDT (Zero Engineering Risk): Every single order undergoes mandatory PMI verification and 100% Ultrasonic Testing (UT). Pipes and high-pressure fittings receive additional strict Hydrostatic and Eddy Current testing to guarantee absolute zero-leakage in toxic/acidic environments.
Custom Dynamic Waterjet & Forging: To eliminate high machining scrap costs on expensive nickel alloys, we supply custom-cut blanks, discs, or custom-forged flanges directly from your blueprints.
