Stainless Steel 310 Wire

Product Description

FUSHUN METAL's Stainless Steel 310 Wire is a premium high-chromium, high-nickel austenitic stainless steel wire specifically engineered for exceptional heat resistance and oxidation resistance at extreme temperatures up to 1150°C (2100°F). With a superior chemical composition featuring approximately 25% chromium and 20% nickel, our 310 wire maintains its structural integrity, strength, and oxidation resistance even during prolonged exposure to high-temperature environments. Available in precision diameters down to 0.10mm, this specialized wire combines excellent high-temperature performance with good formability and weldability, making it the ideal choice for demanding high-temperature applications in industrial furnaces, heat treatment equipment, petrochemical processing, and thermal processing industries. Unlike standard stainless steels that lose their mechanical properties at elevated temperatures, FUSHUN METAL's 310 stainless steel wire delivers reliable performance in extreme heat environments where conventional alloys fail, providing both oxidation and carburization resistance while maintaining dimensional stability under thermal cycling conditions.
