Stainless Steel Sheet Have A Higher Plastic Toughness

Stainless steel plate is generally stainless steel plate and acid-resistant steel plate, since the beginning of this century, to now has 90 years of history. Its surface is smooth, has a high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion. It is a kind of stainless steel is not easy to rust, but not absolutely no rust. Stainless steel plate refers to the resistance to atmospheric, steam and water and other weak media corrosion of steel, and acid-resistant steel plate is acid, alkali, salt and other chemical erosion of corrosion of the plate. Stainless steel plates have high temperature oxidation resistance, but the oxidation rate will be exposed to the environment and product factors such as the inherent factors.

As the stainless steel itself yield points high, high hardness, cold hardening effect is remarkable, stainless steel 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 in the bending compared with the carbon steel has a strong tendency to rebound;

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

4) Because SUS304 stainless steel plate hardness is high, cold hardening effect is significant so in the choice of bending tools to choose the heat treatment hardness should be more than 60HRC tool steel, the surface roughness than carbon steel bending tool height of an order of magnitude.

According to the above characteristics, in general:

1. Unit thickness, the thicker the sheet, the greater the required bending force, and with the increase in plate thickness in the choice of bending equipment, the margin should be greater;

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. In the design of the plate thickness and bending radius of the corresponding circumstances, according to experience, a bending of the workpiece to expand the size of the right side of the addition of minus two thickness, fully meet the design accuracy requirements, according to the empirical formula to calculate the amount of development Simplify the calculation process to 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 bending piece 90 degrees angle, the required angle of the knife to be designed smaller. 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.
