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.
