Relationship between mechanical properties and formability and serviceability To obtain the desired shape of a Steel plate, it must be permanently deformed and the process adopted can be partial or integral bending, deep drawing, tensioning or a combination of these forming methods.
Hot rolled steel products include strips (coils) and steel sheets sheared from them. The steel strip (coil) can be divided into straight hair rolls and finishing rolls (sub-rolls, flattening sub-rolls and slitting strip rolls).
As a result of straight hair volume without re-rolling, not remove the steel strip head and tail size change part and without straightening and leveling, so straight hair volume with tongue and fish tail, and easy to happen head and tail thickness, width uneven, side wave shape, folded edge, tower shape and open volume appear wrinkles (waist fold) and other defects, so the surface quality of the steel plate, plate shape requirements are relatively high use, should not use hot-rolled straight hair volume, but should be selected after finishing line re-roll, leveling of flat volume.
Stainless steel cold rolled steel plate is a stainless steel plate produced by cold rolling process, the thickness is not more than 3mm for thin plate, the thickness is more than 3mm for thick plate. It is used to make corrosion resistant parts, pipelines, containers, medical equipment, marine equipment of petroleum and chemical industry, etc. Its classification and grades are as follows.
