Our thermal processing alloys are used for bar frame baskets, corrugated shrouds, and other fixtures that carry the parts to be heat treated into and out of the furnace. Inside the furnaces, our alloys are used for radiant tubes, fans, muffles, inner covers, belts, etc. RA330 is a workhorse alloy due to its good strength, its resistance to carburization, and its resistance to thermal fatigue after repeated temperature cycling. RA330 is also immune to sigma phase formation so it maintains its ductility allowing for restraightening and/or repair welding to extend the useful life of a fixture. Our alloys are commonly used in a variety of heat treating operations including annealing, vacuum treating, neutral hardening, carburizing, molten salts, and various other applications.
