BAIJIAN - Third party testing organization
Hot rolling is relative to cold rolling. Cold rolling is rolling below the recrystallization temperature、 while hot rolling is rolling above the recrystallization temperature. The width of the steel plate can also be any size in multiples of 50mm or 10mm、 and the length of the steel plate can be any size in multiples of 100mm or 50mm. However、 the minimum length of the steel plate with a thickness of 4mm or less shall not be less than 1.2m、 and the minimum length of the steel plate with a thickness greater than 4mm shall not be less than 2m. According to the requirements、 steel plates with a thickness of less than 30mm can have a thickness interval of 0.5mm. According to the requirements、 after consultation between the supply and demand parties、 other sizes of steel plates and strips can be supplied. Note: The unevenness specified in the table only applies to steel plates with a lower yield point not exceeding 460N/mm2. For steel plates with a yield point exceeding 460N/mm2 and those undergoing quenching and tempering、 the maximum unevenness value is 1.5 times that specified in the table. The sickle bend of the steel strip shall not exceed 3mm per meter. The edge cutting steel plate should be cut into right angles、 and the cutting angle and sickle position should not make the length and width of the steel plate less than the nominal size、 and the minimum rectangle of the nominal size ordered must be ensured. The steel strip should be rolled into coils. Weight: Steel plates and strips are delivered according to actual or theoretical weight. The density of carbon steel calculated by theoretical weight is 7.85g/cm3. Other steel grades shall comply with the relevant standards. W=7.85Xb、 where b is the thickness
