RA RA330®

牌号RA RA330®
厂家Rolled Alloys
分类Nickel
介绍RA330® is the workhorse of the heat resistant alloys. It has good strength, carburization and oxidation resistance to 2100°F. These properties are enhanced by a nominal 1.25% silicon addition. RA330 has been designed to withstand the thermal shock of liquid quenching. RA330 finds wide application in high temperature industrial environments where good resistance to the combined effects of carburization and thermal cycling is a prime requisite. RA330 remains fully austenitic at all temperatures and is not subject to embrittlement from sigma formation.

RA330 is worked by forming and machining procedures similar to those used with the austenitic stainless steels or nickel-chromium alloys. Forming at room temperature is suggested whenever possible. Heat treatment is not necessary after most forming or welding operations. When required, the suggested full anneal is 1900-2050°F, rapid air cool or water quench. RA330 may be readily welded using RA330-04 weld fillers of matching composition. Do not use AWS ER330. Keep interpass temperatures low, do not preheat, do use reinforced stringer beads. Machinability rating 20-25% of B1112.
