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 |
| NH25-35Mic | 850℃-1100℃ | The petrochemical synthesis ammonia, hydrogen,methanol reforming furnace and cracking furnace,DRI reformer radiant tubes,simmer elbows tube |
