Hastelloy® C-22 Straight Wire

Hastelloy® C-22 Straight Wire is a nickel-chromium-molybdenum-tungsten alloy wire designed for superior resistance to both oxidizing and reducing environments. Its excellent immunity to pitting, crevice corrosion, and stress corrosion cracking makes it an indispensable material for chemical processing, marine engineering, and high-performance manufacturing. Supplied in straightened form, it offers precision, machinability, and consistency for welding, joining, and fabrication processes. Specific technologies benefiting from Hastelloy® C-22 straight wire include Nd:YAG laser cladding with automatic wire feeding for extending the service life of marine propellers, where it provides strong bonding and durability; cryogenic treatment processes applied to wire forms, which significantly enhance hardness and wear resistance; and weld overlay applications for chemical reactors and heat exchangers, where its alloy chemistry prevents localized corrosion and ensures long service life. In research, Hastelloy® C-22 wire serves as a critical platform for evaluating microstructure evolution, alloy performance under extreme corrosion, and advanced joining methods. By combining corrosion resistance, thermal stability, and fabrication versatility, Hastelloy® C-22 Straight Wire continues to advance industrial and scientific innovation.
