RA330
RA330
RA330® alloy is an austenitic heat and corrosion resisting alloy offering an exceptional combination of strength and resistance to carburization, oxidation and thermal shock. Carburization and oxidation resistance to 2100°F (1148°C) are enhanced by a nominal 1.25% silicon addition. RA330 alloy finds wide application in high temperature industrial environments where good resistance to the combined effects of carburization and thermal cycling are required. RA330 alloy remains fully austenitic at all temperatures and is not subject to embrittlement from sigma formation.
Applications
Muffles, Corrugated Boxes, Retorts, Bar Baskets, Radiant Tubes
