Hydrogen-handling and hydrogenation equipment
Thread Content
For hydrogen-handling and hydrogenation equipment, determine when to use chromium-molybdenum steel and when to apply 347 cladding; there is equipment designed by a design institute that uses S30403 for welding
I see that for the equipment designed by a design institute, the design temperature is 230; for the equipment made of S30403 through surfacing, the design temperature is also 230
It depends on the medium. It is estimated that the corrosion resistance of S30403 meets the requirements. It is estimated that heat treatment is required at the base layer, so ultra-low carbon stainless steel is used for surfacing.
