Material stamping performance required when producing stainless steel stamping parts

Stamping is a widely used metal processing technology, and stamping parts are basically present in various industries. Stainless steel is one of the most commonly used materials in metal stamping processing. In order to produce qualified stainless steel stamping parts, it is necessary to understand the stamping performance of stainless steel materials. Next, Precision will give you an analysis of the main stamping properties of stainless steel materials. 1) Stainless steel has large stamping deformation resistance and high elastic rebound. In production, refurbishment, correction procedures and necessary heat treatment are often added. 2) Most stainless steel materials have high strength and toughness, and are easy to stick to the mold during stamping. Therefore, care should be taken to maintain the surface finish of the working parts of the concave and convex mold and the sharpness of the cutting edge when drilling. When stamping, the die gap should be small. When bending and stretching, the gap between the concave and convex mold and the mold fillet should be appropriately enlarged. When stamping, lubricating oil with higher viscosity can be used. 3) The cold work hardening of stainless steel stamping parts is serious, and it is easy to produce wrinkles during stretching. Therefore, after each stretching, intermediate annealing is usually required. After the stretching is completed, stress removal annealing should be carried out immediately to prevent the stamping parts from cracking. Heating drawing can also be used for stainless steel stamping parts to reduce the number of drawing times. 4) In the soft state, stainless steel has better stamping performance. The softening heat treatment method of stainless steel: annealing 1Cr13, 2Cr13, 3Cr13, 4Cr13 materials, and quenching 1Cr18Ni9 and 1Cr18Ni9Ti materials.
