Stainless steel shrapnel is an elastic element widely used in machinery and electronics industries. When loaded, stainless steel shrapnel can produce large elastic deformation to convert mechanical work or kinetic energy into deformation energy. After unloading, the deformation of the shrapnel disappears and returns to its original shape. Transform deformation energy into mechanical work or kinetic energy Stainless steel shrapnel is widely used in stamping parts, vacuum tube bullet alarm cards, lamp cards, pipe making, cold bending forming and auto parts and other industries due to its excellent elastic properties and physical properties.
