(1)Welding Wires electrodes shall be subject to 300-350 ° C baking 1h.
Two. Surfacing carbon steel when the preheating temperature above 300 ℃, surfacing low-alloy steel preheating temperature is 400-500 ° C, the surfacing of stainless steel preheating temperature to 600-650 ° C.
(3) low-alloy steel and stainless steel after Welding Accessoriesshall be subject to 700 ° C annealing.
Uses: Used to working to maintain good wear resistance and corrosion resistance of the occasion at about 650 ℃, or withstand the shocks and hot and cold staggered parts, such as surfacing high-temperature high-pressure valves and hot shear blades.
