How to Bend 304 Stainless Steel Bars for Mechanical Parts
Stainless steel bar mechanical parts are widely used in our daily life, such as anti-theft windows, shutters, shelves, etc. Due to the high yield point, high hardness and obvious cold work hardening effect of mechanical parts stainless steel bars, the bending process of stainless steel bars and plates has some distinct characteristics.
A mechanical part requires a large deformation force due to the poor thermal conductivity and low elongation of the stainless steel bar. Compared with carbon steel bars, stainless steel bars have a stronger tendency to spring back when bent. Due to the low elongation of stainless steel bars, the bending angle R is greater than that of carbon steel when bending, otherwise cracks may occur; due to the high hardness of SUS304 stainless steel bars, the cold work hardening effect is obvious. Therefore, when selecting bending tools, tool steel with heat treatment hardness greater than 60HRC should be selected, and its surface roughness is an order of magnitude higher than that of carbon steel bending tools.

The greater the yield strength of the stainless steel bar for mechanical parts, the greater its elasticity and recovery. In order to obtain a 90-degree angle of the bending part, the angle of the pressing knife should be designed to be smaller. The bending angle of stainless steel with the same plate thickness is larger than that of carbon steel, so special attention should be paid, otherwise bending cracks will occur, which will affect the strength of the workpiece.
