Metal file cabinet material introduced
Oct 15, 2016

Metal file cabinet made of cold-rolled steel plate. Cold rolled hot rolled coils as raw material, rolling at room temperature, cold-rolled steel sheet through production of cold-rolled steel sheet, commonly known as the cold plate. Cold-rolled sheet thickness is between 0.1-8.0mm.
Features: has not been annealed, high hardness (HRB is greater than 90), extremely poor machinability, only simple directional bending of less than 90 degrees (perpendicular to the rolling direction). Because cold rolling the original volume is more brittle, less suitable for processing, so typically cold-rolled steel sheet requirements after annealing and surface treatment.
Cold-rolled steel sheet is the abbreviation of cold-rolled plain carbon structural plate, is made of ordinary carbon structural steel hot rolled steel strip, after further cold rolling steel plate thickness is less than 4mm. Due to the rolling at room temperature, do not produce iron oxide, so cold plate surface quality, high dimensional accuracy, coupled with the annealing, mechanical and technological properties are superior to hot-rolled steel sheet, in many areas, especially household electrical appliance manufacturing, has been gradually replaced with its hot-rolled steel sheet.
