First, the classification of steel plate (including strip):
1, according to the thickness of classification: (1) thin plate (2) plate (3) thick plate (4) special thick plate
2, according to the production method: (1) hot-rolled steel plate (2) cold-rolled steel plate
3, according to the surface characteristics of classification: (1) galvanized sheet (hot galvanized sheet, galvanized sheet) (2) tin plate (3) composite steel (4) color coated steel)
4, according to the use of classification: (1) bridge steel plate (2) boiler steel plate (3) shipbuilding steel plate (4) armor plate (5) automotive steel plate (6) roofing steel plate (7) structural steel plate (8) electrical steel plate (silicon steel sheet) (9) spring steel plate (10) other
Second, common Japanese grades in general and mechanical structural steel plate
1, Japanese steel (JIS series) in the grade of common structural steel mainly consists of three parts: the first part of the material, such as: S (Steel) that the steel, F (Ferrum) that the iron; the second part of the different shapes, types, and uses, such as P (Plate) that the plate, T (Tube) that the tube, K (Kogu) that the tool; the third part of the characteristic The third part indicates the characteristic number, generally tensile strength. Such as: SS400 - the first S said steel (Steel), the second S said “structure” (Structure), 400 for the lower limit of tensile strength of 400MPa, the overall tensile strength of 400MPa of the ordinary Structural steel.
2, SPHC - the first S for the abbreviation of steel Steel, P for the abbreviation of plate Plate, H for the abbreviation of heat Heat, C for the abbreviation of commercial Commercial, the whole of the general hot-rolled steel and steel strip.
3, SPHD - hot rolled steel plate and strip for stamping.
4、SPHE--indicates hot rolled steel plates and strips for deep drawing.
5, SPCC - cold rolled carbon steel sheet and strip for general use, equivalent to China Q195-215A grade. The third letter C for the abbreviation of cold Cold. Need to ensure that the tensile test, add T at the end of the grade for SPCCT.
6, SPCD - said stamping cold rolled carbon steel sheet and strip, equivalent to China's 08AL (GB/T13237-1991) quality carbon structural steel.
7、SPCE--Indicates cold rolled carbon steel sheet and strip for deep drawing, equivalent to China SC1 (GB5213-2001) deep drawing steel. Need to ensure that the non-ageing, at the end of the grade plus N for SPCEN. Cold rolled carbon steel sheet and strip tempering code: annealed state A, standard tempering for S, 1/8 hard for 8, 1/4 hard for 4, 1/2 hard for 2, hard for 1. Surface finish code: non-glossy fine-rolled for D, bright fine-rolled for B. Such as SPCC-SD said the general use of cold rolled carbon steel sheet with standard tempering, non-glossy fine-rolled. And then SPCCT-SB said standard tempering, bright processing, the requirements of the mechanical properties of cold-rolled carbon sheet.
8, JIS mechanical structural steel grade is expressed as: S + carbon content + letter code (C, CK), of which the carbon content with the median value × 100, the letter C: represents carbon K: represents carburized steel. For example, the carbonization coil S20C has a carbon content of 0.18-0.23%.
