SPCC Cold Colled Steel Plate

Cold rolled Discription :
Cold-rolled, hot-rolled steel coil for raw material, after acid pickling to remove oxide skin for cold rolling, the finished product is hard, because of cold work hardening caused by deformation of continuous cold rolling hard roll strength, increase hardness, toughness and plastic index decreased, so the stamping performance will deteriorate, can only be used for simple deformation of the parts.Hard coil can be used as a raw material, hot dip galvanized factory for hot dip galvanizing unit Settings are annealed wire.Hard coil weight generally in June to 13.5 tons, steel at room temperature, for continuous rolling of hot rolled pickling volumes.Inner diameter is 610 mm.
Product features: because there is no after annealing treatment, the hardness is very high (HRB is greater than 90), mechanical processing performance is poor, only simple has directivity of less than 90 degree bend processing (perpendicular to the direction of the winding).
Simpler, cold-rolled, is on the basis of hot-rolled coil processing rolling out, in general is hot-rolled pickling - - cold rolling process.
Cold rolling is under the status of the processed by hot rolling plate, while in the process of machining for rolling will make the steel plate temperature, nonetheless called cold rolling.Because of the variant of cold-rolled, hot-rolled after a cold in with poor mechanical properties, hardness is too high.Must pass through annealing to restore its mechanical properties, without annealing called hard rolls.Hard coil is commonly used to do without bending, stretching products
