Cold rolled steel plate after its strength, increase hardness, plasticity index, stamping performance is poorer, must can restore its mechanical properties after annealing. Now that is commonly used in sheet metal factory manufacture are after annealing treatment of manufacture, its mechanical properties and process performance are better than that of the hot rolled steel, and good surface quality and dimensional accuracy.
(1) the domestic manufacture
Usually divided into three categories: cold rolled steel sheet, high quality cold-rolled steel plate, deep drawing with cold-rolled steel sheet.
Cold rolled steel sheet: commonly used brand have: Q195, Q215, Q235, Q275
Q: ordinary carbon structural steel yield point of the code
195215235275, respectively, the value of the yield point. Unit: MPa (N/was)
Q235 in brand with its good strength, plasticity and weldability, etc. Comprehensive mechanical properties, can better meet the demand of normal production, the most widely applied in industrial production.
High quality cold rolled steel sheet: commonly used brand: 08 preceding F, 10, 10 F
08, 10 said the carbon content of steel
F not rimmed steel deoxidized. B said half killed steel z said general deoxidizing killed steel
08 f has good plasticity and stamping performance, commonly used to make tensile structure of sheet metal parts.
Deep drawing with cold-rolled plates: commonly used brand: 08 al
Said the carbon content of steel 08 Al said using aluminium killed steel deoxidized
(2) the cold-rolled steel sheet
Commonly used brand: (SPCC) SPCD SPCE
P: S: steel (steel) plate (plate) C: cold (cold) C: ltd. (business)
D: deep drawn (tensile) E: deep drawn extra (deep drawing)
Heat treatment condition: S: A annealing annealing + is flat and level
8:1/8 hardness 4:1/4 hardness 2:1/2 hardness
Drawing level: F: ordinary drawing level HF: drawing high level government supreme drawing level
(3) German cold-rolled steel grades
Commonly used brand: st12, st13, st14 st14 -t, st15.
St: steel (steel)
13:12: cold-rolled steel plate stamping cold rolled steel sheet
14: deep drawing level 15: cold rolled steel sheet deep drawing level cold-rolled steel sheet 14 - T: super cold rolled steel sheet
(4) common cold rolled steel plate joint of the following:
Material level
National standard JIS standard German DIN American ASTM standard European standard EN commercial level
In order to ensure product quality, Beijing Riseboyo Science ﹠ Technology Development Co., Ltd. chassis cabinets for production of cold rolling steel plate adopts the rolling steel line of angang new steel cold rolled steel sheet.
