Post-weld heat treatment For welded parts with large thickness stainless steel plates, post-weld heat treatment eliminates welding residual stresses. However, it should be noted that the heat treatment temperature, the carbon steel side will constitute the iron body decarburization, so that the progress of the lower.galvanized iron wire 2mm stainless steel wire And in the stainless steel side is carburized and hardened, the formation of impact toughness reduced, become the risk of failure of welded joints, which is not desirable.2B finish 201 grade stainless steel sheet Proper heat treatment can eliminate the residual stress of welding, nor does it affect the corrosion resistance of the coating. The method is: the heat treatment of the large order or stiffness of the stainless steel plate welding components, should be in the bottom of the end of the welding, the detection of the internal and surface quality of the paste are qualified after heat treatment, and the temperature should not exceed 400 degrees,stainless Steel pipe fitting 45 degree At this temperature, the holding time can be slightly extended.With this temperature after the welding treatment, the residual stress can be reduced by about 40%, together will not affect the coating of stainless steel turbidity function between the coating and the underlying carbon Expansion of the heat is not easy to attack in the heat treatment is completed before the welding layer and the thickness of the coating of stainless steel plate punching network products. After the cladding is finished, no heat treatment is required.1.50 mm thickness stainless steel plate |
