Super 304H, UNS S30432, high strength, high steam oxidation resistance, austensitic stainless steel pipes
- high strength among 18Cr-8Ni austensitic stainless steels utilizing Cu-rich phase
- fine grained microstructure by thermo mechanical process, which contributes to superior steam oxidation
- resistance to conventional coarse grainzed TP347H stainless steel pipes, tubes.
- Superior welding ability to TP347H stainless due to smaller amount of Nb
- Good phase stability proven by long term creep rapture tests and actual operation in boilers
