The use of stainless steel plates is very wide. In different application fields, stainless steel plates can be processed into any desired style. How does the stainless steel plate manufacturer bend the stainless steel plate? What should be paid attention to when bending?

Due to the high yield point and high hardness of stainless steel itself, the cold work hardening effect is significant. The characteristics of stainless steel plates when bent are as follows:

1. Because the thermal conductivity is poorer than ordinary low carbon steel, the elongation is low, resulting in a large required deformation force;   

2. Compared with carbon steel, stainless steel sheet has a strong tendency to rebound;   

3. Due to the low elongation of stainless steel plate compared to carbon steel, the bending angle R of the workpiece during bending is greater than that of carbon steel, otherwise there is a possibility of cracks;   

4. Due to the high hardness of the stainless steel plate and the significant effect of cold work hardening, the tool steel with heat treatment hardness of 60HRC or more should be selected when selecting the bending tool, and its surface roughness is an order of magnitude higher than that of the carbon steel bending tool.

According to the characteristics of the above stainless steel plate during bending, the following conditions should be noted during operation;

1. Under the unit size, the thicker the stainless steel plate, the greater the bending force required, and as the plate thickness increases, the bending force margin should be greater when selecting the bending equipment;   

2. Under the unit size, the greater the tensile strength and the smaller the elongation, the greater the required bending force and the larger the bending angle;   

3. In the case where the plate thickness corresponds to the bending radius in the design drawing, according to experience, the unfolding size of a curved workpiece is the addition of the right-angle side minus two plate thicknesses, which can fully meet the design accuracy requirements. The unfolding amount can be calculated according to the empirical formula. Simplify the calculation process and greatly improve production efficiency;   

4. The greater the yield strength of the material, the greater the amount of elastic recovery. In order to obtain the 90-degree angle of the bending piece, the smaller the angle of the pressure knife needs to be designed. Compared with carbon steel, stainless steel with the same plate thickness has a large bending angle. Special attention should be paid to this. Otherwise, bending cracks will occur, which will affect the strength of the workpiece.
