6.Processing technology of stainless steel square steel:

a) Drawing deep processing: it is easy to generate frictional heat, so use stainless steel with high pressure resistance and heat resistance, and remove the oil attached to the surface after the completion of the molding process.

b) Welding: Before welding, the rust, oil, water, paint, etc. that are harmful to welding should be completely removed, and the welding rod suitable for the steel type should be selected. The spot welding time interval is shorter than that of carbon steel spot welding. Stainless steel brush should be used to remove welding slag. After welding, in order to prevent local corrosion or strength reduction, the surface should be polished or cleaned.

c) Cutting and stamping: Since stainless steel has higher strength than general materials, higher pressure is required for stamping and cutting. When the gap between the knife and the knife is accurate, poor shearing and work hardening will not occur. Plasma or laser cutting is best When gas cutting or arc cutting has to be used, the heat-affected zone is ground and heat treatment is necessary.
