Heat Resistant Steel Casting

Heat Resistant Steel Casting mainly heat resistant casting alloy and heat resistant stainless steel,heat-resistant corrosion resistant alloy material.

Our heat Resistant steel casting usually centrifugal casting tubes and used in industrial furnaces,especially for DRI furnace,petro chemical reformering furnace and cracking furnace

Features and applications of heat resistant steel casting tube by centrifugal cast tubes
Designation	Applicable tempreture℃	main applications
NH25-20	650℃-950℃	A small amount of ferrite in the metal structure of NH25-20,which with good oxidation resistance and weak thermal shock resistance.As furnace tube when temperature under 950℃,as furnace structure parts when temperature under 1150℃
NH20-32Nb	850℃-1000℃	Good ductility after ageing.For parts located outside of furnace;reformer furnace manifolds;transfer line and cracking simmer elbow tube etc
NH25-35Nb	850℃-950℃	The petrochemical synthesis ammonia,hydrogen,methanol reforming furnace and cracking furnace,DRI reformer radiant tubes,simmer elbows tube
NH25-35W	850℃-1080℃	The petrochemical synthesis ammonia, hydrogen,methanol reforming furnace and cracking furnace,DRI reformer radiant tubes,simmer elbows tube
