Hastelloy Alloy Steel Round Bar Hastelloy C-22 is a premium-grade nickel-chromium-molybdenum alloy designed for superior corrosion resistance in extreme chemical environments. Known for its outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, Hastelloy C-22 provides reliable performance across a wide range of oxidizing and reducing media.
Manufactured according to ASTM B574 and other international standards, Hastelloy C-22 round bars deliver exceptional mechanical strength, excellent weldability, and long-term stability under harsh service conditions. The alloy’s high chromium content enhances its performance against oxidizing agents, while molybdenum and tungsten improve its resistance to reducing media. Hastelloy C-22 is particularly effective in environments containing wet chlorine gas, acetic acid, formic acid, ferric and cupric chlorides, seawater, and mixed industrial chemicals.
Exceptional Corrosion Resistance: Superior protection in oxidizing, reducing, and mixed chemical environments.
High Strength and Durability: Maintains mechanical integrity over a wide range of temperatures and pressures.
Excellent Fabrication Characteristics: Suitable for welding and forming without compromising corrosion resistance.
Thermal Stability: Consistent performance under thermal cycling and fluctuating operating conditions.
