Stainless steel plate to avoid cracking
Now the market for high temperature stainless steel plate demand is very big, and some manufacturers because of the technology is not up to, in the processing of high temperature stainless steel plate, or the possibility of cracking, how to process high temperature stainless steel plate?
The following high - temperature stainless steel plate manufacturers senior technicians to talk about how to avoid this situation in the processing.
High temperature stainless steel plate welding: before welding should thoroughly remove harmful to the welding rust, oil, water, paint, etc. The spot welding time interval is shorter than that of carbon steel. Stainless steel brush should be used to remove the welding slag of high temperature resistant stainless steel plate.
High temperature stainless steel plate after welding, in order to prevent local corrosion or strength decline, the surface should be grinding treatment or cleaning. High temperature resistant stainless steel plate cutting and stamping: because stainless steel is higher than the general material strength, so the stamping and shearing need higher pressure, and knife and knife clearance is accurate in order not to occur when the shear bad and processing hardening.
High temperature resistant stainless steel plate is best to use plasma or laser cutting, when you have to use gas cutting or arc cutting, the heat affected area for grinding and necessary heat treatment.
High temperature resistant stainless steel plate bending processing: book plate bending to 180, but in order to reduce the surface crack with radius of 2 times the thickness of the best size, the plate along the rolling direction to 2 times the radius of thickness, high temperature resistant stainless steel plate with a rolling vertical bending to 4 times the thickness of the radius is necessary, especially at welding, in order to prevent cracking deal with welding processing zone in surface grinding.
