SUH310 heat-resistant steel
Standard: JIS (G 4311 Heat steel bar)
Grade: SUH310
● SUH310 features and applications:
SUH310 heat-resistant steel, Japanese JIS standard series of heat-resistant austenitic steel. SUH310 than SUH309 antioxidant (1150 ℃ or less) is good, and higher high temperature strength, so, for heat exchangers, high temperature furnace car parts and chemical devices. SUH310 equivalent to Chinese GB 2Cr25Ni20, U.S. ASTM / AISI 310/UNS S31000, the German DIN CrNi2520/X12CrNi25.21.
