Stainless Steel Sheet Bend Its Characteristics

As the Stainless Steel Sheet itself yield points high, high hardness, cold hardening effect is remarkable, Stainless Steel Sheet plate bending characteristics are as follows:

1) due to thermal conductivity than ordinary low carbon steel, low elongation, resulting in the required deformation of large;

2) 321 Stainless Steel Sheet sheet in the bending and carbon steel compared to a strong tendency to rebound;

3) Stainless Steel Sheet plate relative to the carbon steel due to low elongation, bending the workpiece bending angle R is greater than carbon steel, or there may be cracks;

4) Since the SUS304 Stainless Steel Sheet plate of high hardness, significant work hardening effect in the choice to select the tool bending heat treatment should reach a hardness 60HRC tool steel, carbon steel than the surface roughness of the bending tool an order of magnitude.

According to the above characteristics, in general:

1. The size of the unit, the thicker the plate, the greater the required bending force, and with increasing thickness off bending force when selecting the margin should be larger folding apparatus;

2. Unit size, the greater the tensile strength, the smaller the elongation, the greater the required bending force, the greater the bending angle should be;

3. The design of plate thickness corresponding to the case where the bending radius, according to experience, expand the size of a workpiece bent by subtracting the sum of two right-angle side sheet thickness, the design can meet the accuracy requirements, the amount of calculation can be deployed according to the empirical formula Simplify the calculation process to greatly improve the production efficiency;

4. The greater the yield strength of the material, the greater the amount of spring back, in order to obtain an angle of 90 degrees bent parts, the smaller the pressure required for the knife angle will design. Relative to the same thickness of carbon steel stainless steel bending angle is larger, this should pay special attention to the case will appear bending crack, affecting the workpiece strength.
