Stainless steel products are very common, because it is not easy to rust corrosion, its range of application is also very wide, the following is about stainless steel plate processing how to bend?
Stainless steel can be bent when heated to a hot red. Due to the poor thermal conductivity and low elongation than ordinary low carbon steel, the required deformation force is large; Compared with carbon steel, 321 stainless steel plate has a strong Zhidao rebound tendency during bending. Stainless steel plate relative to carbon steel due to low elongation, bending workpiece bending Angle R is greater than carbon steel, otherwise there is the possibility of cracking.
Due to the high hardness of stainless steel plate, cold hardening effect is significant, so in the choice of bending tool should choose tool steel whose heat treatment hardness should reach more than 60HRC, the surface roughness of which is an order of magnitude higher than the internal bending tool of carbon steel.
Due to the poor tempering stability, the carbon steel in the tempering treatment, in order to ensure the higher strength of the tempering temperature should be used, so that the toughness of the steel is low; In order to ensure good toughness, the strength is low when the tempering temperature is high, so the comprehensive mechanical properties of carbon steel is not high.
