Super austenitic Industeel

Highly alloyed iron nickel chromium stainless steels containing molybdenum have been developed to respond to severe corrosion specifications. Superaustenitic stainless steels exhibit great resistance to chloride pitting and crevice corrosion because of high molybdenum content (>6%) and nitrogen additions, and the higher nickel content ensures better resistance to stress corrosion cracking

Fireside Corrosion Behaviors of Super304H and HR3C in

May 16, 2018 · The corrosion behaviors of Super304H and HR3C used for USC boiler applications were investigated in simulated coal ash/gas environments with 0.1 and 1.5% of SO 2 at 650 °C for 500 h. The results indicated that the increase in SO 2 accelerated the corrosion rate and the spalling tendency of the corrosion layer in both tested alloys.

US Suppliers for Code Case 2328 stainless tubing Steel

Dec 21, 2006 · The Super304H is specified for boiler superheater tubing by IHI. I had hoped to find suppliers other than in Japan, due to the difficulty in purchasing small quantities of the material there. We will simply have to push IHI to provide spare material and the quantities required for qualification of procedures and welders per the Code Case.
