What should be paid attention to in the process of stainless steel processing

1、 Cold drawing deep processing is easy to produce friction heat, so the use of high pressure, heat resistance stainless steel pipe at the same time, after the end of the molding process should remove the oil attached to the surface.

2、 Before welding, rust, oil, water, paint, etc. harmful to welding shall be removed, welding rod suitable for steel grade shall be selected. The time interval of spot welding is shorter than that of carbon steel. Stainless steel pipe brush should be used to remove welding slag. After welding, the surface shall be ground cleaned to prevent local corrosion strength reduction.

3、 Cutting stamping. Because the strength of stainless steel pipe is higher than that of general materials, higher pressure is required in stamping shearing. When the gap between the cutter cutter is accurate, the bad shear work hardening will occur. Plasma laser cutting is used. When gas cutting arc cutting is necessary, the thermal affected Zone shall be ground heat treated.

4、 For stainless steel pipe bending, the thin plate can be bent to 180. However, in order to reduce the crack on the bending surface with the size of twice the thickness of the plate, it is necessary to give a radius of 2 times the thickness of the plate along the rolling direction a radius of 4 times the thickness of the plate when bending in the vertical direction of the rolling. Especially in the welding process, the surface grinding of the welding area should be carried out in order to prevent processing cracking.

5、 Pay attention to prevent scratch pollutant adhesion during construction. Stainless steel construction shall be carried out under the condition of film sticking. However, with the extension of time, the residual adhesive liquid shall be in accordance with the service life of the film. After the construction, the surface shall be washed when removing the film, special stainless steel pipe tools shall be used. When it is used with general steel cleaning public tools, cleaning shall be carried out in order to prevent iron filings sticking.

6、 Attention should be paid to let the strong corrosive magnetic stone luxury cleaning drugs contact the surface of the stainless steel pipe, if contact should be washed immediately. In order to prevent scratch pollutant adhesion during construction, stainless steel construction is carried out under the condition of film sticking. However, with the extension of time, the residual adhesive liquid shall be in accordance with the service life of the film. After the construction, the surface shall be washed when removing the film, special stainless steel pipe tools shall be used. When it is used with general steel cleaning public tools, cleaning shall be carried out in order to prevent iron filings sticking.
