RA330®
RA330® is a patented alloy designed specifically for the heat treatment industry, and to this day RA330® still outperforms the generic version made only to UNS N08330. In addition to meeting the requirements of UNS N08330, Rolled Alloys has tighter chemistry restrictions and proprietary heat treatments to produce an optimum product. Even the weld wire, RA330-04, has increased levels of manganese to avoid hot cracking. When buying a heat resistant alloy, insist on quality, insist it is RA330®.
RA330® alloy is an austenitic heat and corrosion resistant 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.
