7x7 304 Stainless Steel Spring Wire Nylon Coated AISI 201 410

1. Introduction

Stainless steel wire drawing stress state for the two compressive stress has been tensile stress of the three principal stress state, it and three are compressive stress of the principal stress state, compared to the drawn wire is easier to achieve plastic deformation state. The deformation state of drawing is the main three-way deformation state from the two-way compression deformation to the tensile deformation, which is unfavorable to the plasticity of metal materials and easy to produce and expose surface defects. The amount of pass deformation in the wire drawing process is limited by its safety factor, and more passes are drawn when the amount of pass deformation is small. Therefore, multi-pass continuous high-speed drawing is often used in the production of wire.
