Cutting and stamping:
Due to the high strength stainless steel than ordinary materials, so it is more the need when punching and shearing stress, and a knife and knife gap accurately can not occur when the shear and work hardening, had better use the laser plasma or cut off, when have to use gas cutting or arc cutting, grinding was carried out on the heat affected zone and the need for heat treatment.
Bending processing
Book plate can be bent to 180, but in order to reduce the bending surface crack with the radius size of the best 2 times the plate thickness, thick plate along the calendering direction to 2 times the plate thickness radius, and the calendering vertical direction bending to 4 times the plate thickness radius is necessary, especially in the welding, in order to prevent processing cracking should be welded area surface grinding.
Drawing processing
Deep processing is easy to produce friction heat, so the use of high pressure and heat resistance stainless steel at the same time after molding should remove the oil attached to the surface.
welding
Before welding, rust, oil, water, paint, etc. harmful to welding should be completely removed, and welding rod suitable for steel grade should be selected. Spot welding time distance is shorter than carbon steel spot welding distance, remove welding slag should use stainless steel brush.
After welding, the surface should be ground or cleaned to prevent local corrosion or loss of strength.
Construction and construction attention points
In order to prevent scratches and contaminants attached to the construction, stainless steel processing under the state of film. But with the extension of time, the residual paste liquid in accordance with the film use period, after the construction to remove the film should be surface washing, and the use of special stainless steel tools, and general steel cleaning tools, in order not to let the iron filings stick should be cleaned.
Care should be taken not to allow strong corrosive magnetic and stone luxury cleaning drugs to contact the surface of stainless steel, if contact should be immediately washed. After construction, neutral detergent and water are applied to wash the cement and powder ash attached to the surface.
