How to bend stainless steel plate

Because the thermal conductivity is worse than ordinary carbon steel, the elongation is low, leading to the required deformation force; 321 stainless steel sheet has a strong springback tendency compared with carbon steel in bending; ​stainless steel plate relative to carbon steel due to low elongation, bending workpiece bending Angle R is greater than carbon steel, otherwise there may be cracks.

Due to the high hardness of stainless steel plate, the cold hardening effect is significant, so in the selection of bending tool to choose the heat treatment hardness should reach 60HRC above tool steel, its surface roughness than carbon steel bending tool is an order of magnitude higher.

After alloying elements are added to steel, the basic components of steel, iron and carbon, will interact with the alloying elements. The purpose of steel alloying is to improve the microstructure and properties of steel by the interaction of alloying elements with iron and carbon and the effect on the phase diagram of iron and carbon and the heat treatment of steel. To increase the strength, we must try to increase the resistance of dislocation movement. The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine crystal strengthening, and second phase (precipitation and dispersion) strengthening. The strengthening effect of alloying elements makes use of these strengthening mechanisms.
