Material and application

The STBA22 is used to transfer high temperature outside and inside the boiler. Chrome-molybdenum steel for the material. A steel pipe at a factory or the like that requires the use of steam is necessary, but not carbon steel, but the use of such alloy steel is limited when high temperature strength is required.


Heat Treatment


In the specifications, low-temperature baking, isothermal burning, complete baking, baking after the fire, but the electric resistance welded steel pipe (welded steel pipe) is not low-temperature baking.
