Several forming processes for stainless steel angles

1 . Cold forming

It is recommended that forming should be carried out as far as possible below 600 degrees Fahrenheit. When carrying out hot forming process, the entire material should be heated in the temperature range of 1750F to 2250F, stainless steel angles are very soft at this temperature. If the temperature is too high, the angle alloy tends to be hot torn. If it is below this temperature, the austenite will fracture. When the temperature is below 1700F, the intermetallic phase forms rapidly due to the temperature and deformation. Immediately after hot forming, the alloy should be solution annealed at a low temperature of 1900F and quenched to restore its phase equilibrium, toughness and corrosion resistance. We do not recommend stress relieving, but if necessary, the material should be solution annealed at a low temperature of 1900, followed by rapid condensation and water quenching.

2. Hot forming

Angle can be cut and cold formed. However, due to the strength and high hardness of stainless steel angles, it requires more cold forming than austenitic steel, and because of its strength, the springback factor should be fully considered.

3. Heat treatment

Angle steel should be annealed at a low temperature of 1900 degrees Fahrenheit, then quickly condensed and quenched in water. This treatment is suitable for solution annealing and stress relieving. If the stress relief treatment is carried out at a temperature below 1900, it will easily lead to the precipitation of harmful metallic or non-metallic phases.

4. Mechanical machinability

In high-speed machine tools, the feed rate and cutting speed of stainless steel angle and 316L the same. Compared with 316L, if the use of carbonized knife, cutting speed can be reduced by about 1/5, the performance of machinery and its components in the role plays a key role.

5.Fusing

The fusion splicing of angle steel is very good. Not angle steel performance is fusion spliced metal and heat-denatured parts still maintain the same corrosion resistance, strength and toughness with the parent material. Stainless steel angle fusion is not difficult, but its fusion process should be designed to ensure that the fusion can maintain a good phase equilibrium, to avoid the precipitation of harmful metal or non-metallic phase.
