As an Alloy Seamless Steel Tubing Supplier , share with you. Stainless steel products often have various cracking phenomena during the drawing process. Among them, lateral or point cracking of the side walls is a common form of processing failure of 304 stainless steel products with relatively deep drawing such as vacuum cups and pressure cookers. Especially in recent years, the product processing process has been continuously promoted. For example, the number of drawing passes of the thermal insulation cup has been reduced from 5 times to 3 times commonly used at present, from multiple annealing in the middle to one annealing or no annealing after the completion of stamping. Therefore, higher requirements are imposed on the formability of stainless steel materials. The occurrence of lateral or point-like cracking defects on the side walls of stainless steel products may be caused by intercrystalline defects of materials, delta ferrite and other materials, or it may be caused by ...
