Heat Treatment

FUJINAWA product is mainly used for baskets, shrouds and other parts for transport into the industrial furnace heat treatment apparatus. In the industrial furnace, our alloy is mainly used for radiation control, fan, muffle furnace, the inner cover, belt and so on. RA330 because of its high strength, carburization resistance and has a high resistance to thermal fatigue performance under cyclic temperature alloy as a device for heavy duty use. RA330 is not affected by Sigma phase, so it’s malleable so that it can expand and contract or extend the effective life of the weld forming. Our alloys are widely used in hot work environments, including annealing, vacuum heat treatment, neutral hardening, carburizing, and other molten salt environments.

Many sintered alloy muffle furnace usually use RA330,601, RA333, RA602CA and 601 manufacturing industries muffle furnace and baskets, aimed at reducing molybdenum and tungsten powders.Power plant coal thermal power plants requires not only the alloy has good resistance to oxidation and high-temperature strength, but also must be able to resist corrosion and friction caused by vulcanization. In a lot of use, the low nickel content of the alloy can often have better resistance to corrosion than the nickel sulfide-based alloys, such as 309 and 310 stainless steel and alloy RA253MA would normally be used to make a nozzle, burner, burners, pipe cap, pipe supports , measuring tube and soot blowers.Chemical and oil refinery in the Red Coil refining crude oil distillation before the heat treatment. 310 stainless steel is usually used as a burner oil heater on, 310, RA253MA and RA330 slabs will be used on pipe supports and hangers. Treatable alloys are often used in the manufacture of fire tongue to eliminate oxidation and gas refineries produced.
