How to avoid lateral or point cracking on the side wall of 304 stainless steel products 2018-10-23 　　 The lateral or point cracking phenomenon on the side walls of 304 stainless steel products is mainly caused by inclusions or delta ferrite in the material matrix, so in The following two points should be controlled during the manufacturing process of stainless steel: 　　　　 (1) Improve the purity of the material and reduce the content of inclusions in the stainless steel material matrix.　　　　 (2) Improve the composition design and hot and cold rolling annealing process to reduce the content of δ ferrite in the stainless steel material matrix. However, because stainless steel materials inevitably have these two manufacturing defects during the production process, appropriate process measures can also be taken during the processing of vacuum cups and other products to reduce or avoid inclusions or delta ferrite defects. Cracking phenomenon: 　　　　 (1) Change the forming method from thinning drawing to equal thickness drawing.　　　　 (2) Increase the number of deep drawing passes, increase the radius of the die fillet, and reduce the difficulty of material deformation.　　　　 (3) Appropriately increase the viscosity of the drawing oil to promote uniform deformation of the material and avoid excessive stress concentration.
