Stainless steel processing and construction

Cutting and punching due to the high strength stainless steel than ordinary materials, so the punching and shearing need higher pressure, and a knife and knife gap accurately can not occur when the shear and work hardening, had better use plasma or laser 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. Plate bending processing book can bend up 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, and rolling vertical bending to 4 times the thickness of the radius is necessary, especially at welding, in order to prevent cracking for welding area surface grinding machining. Deep Drawing deep Drawing is easy to produce friction heat so it use pressure, high heat resistant stainless steel after the kind of processing at the same time should get rid of the surface of the oil. Before welding welding should be thoroughly get rid of the rust, oil, water harmful to welding, paint, etc. , selected suitable electrode steel grade. From spot welding time shorter than carbon steel welding spacing, get rid of stainless steel brush should be used when welding slag. After welding, in order to prevent the local corrosion or intensity drops, dealing with the surface of ground treatment or cleaning. Construction and construction attention points in order to prevent scratch and pollutants are produced when the attached sticker under the condition of stainless steel construction. But with the extension of time, the paste liquid residue to use time limit for the sticker, get rid of sticker should carry on the surface after washing, construction and use of special stainless steel tools, and general steel clean utility tool, in order not to let the iron stick should be cleaned. Should pay attention to not let has a strong corrosive magnetic and stone luxury clean with drugs come into contact with the surface of stainless steel, if the contact should be immediately when washing. After the construction application of neutral detergent and water washing, the blues until the surface of cement.
