Centrifugal Casting Radiant Tube 1.4848 full types produce and supply(W-type,U-type,O-type,L-type,I-type,P-type,S-tpe)
1.4848 Steel tube usually as furnace tube,Centrifugal Casting Radiant Tube usually are working at high temperature environment on average: 650° C-950° C. 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° C,as furnace structure parts when temperature under 1150° C
Therefore most of them are used for indirect heating to furnace like CAL (continuous annealing line). Similarly CGL (continuous galvanizing line).
