Nickel alloy wire RA330®

rodtube

RA330® is a patented alloy designed specifically for the heat treatment industry. To this day RA330® 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 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. Rolled Alloys and our RA330® alloy were both created to service the need of the thermal process industries for a reliable source of a wrought alloy that could handle the rigors high temperature carburizing conditions and repeated quenching. Both our company and our RA330® alloy product began as parts of the Michigan Steel Castings Company (MISCO). The predecessor to RA330® was an alloy known as MISCO metal, it was a rolled version of the cast HT alloy and 35% nickel, 15% chromium. Its success came as a replacement to castings which were less ductile and fractured during harsh temperature cycling.
