Profile: Rolled Alloys Ltd specializes in offering speciality alloys. We provide plate, sheet, bar, pipe, fittings, & welding materials that are maintained in heat resistant, corrosion resistant, and high temperature alloys. RA330® is an austenitic heat and corrosion resisting nickle alloy offering an exceptional combination of strength & resistance to carburization, oxidation and thermal shock. Carburization and oxidation resistance to 2100°F are enhanced by a nominal 1.25 percent silicon addition. RA330 finds wide applications in high temperature industrial environments where good resistance to the combined effects of carburization and thermal cycling is a prime requisite. RA 330 remains fully austenitic at all temperatures and is not subject to embrittlement from sigma formation.
