ASME SA213/SA213M-2023, specification for seamless ferritic and austensitic alloy steel
boiler, superheater, and heat exchanger tubes.

UNS S30432, CODE CASE 2328, austensitic stainless steel seamless tubes

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
