A, the classification of the steel sheet (including strip)

1, according to the thickness of classification: (1) (2) (3) the plate plate plate plate (4)
2, according to the classification of production methods: (1) hot rolled steel plate (2) cold rolling steel plate
3, according to the classification of surface features: (1) the galvanized, hot galvanized, electric galvanized sheet (2) the tinplate (3) composite plate (4) color coating steel plate

Second, ordinary and mechanical structure with steel plate in common Japanese brands

1, Japanese (JIS series) Steel grades in the normal structural Steel mainly consists of three parts: the first part of the said material, such as: S (Steel) said Steel, F (Ferrum) said iron; Said the second part of different shapes, types, USES, such as P (Plate), T Tube (Tube), K (Kogu) tools; The third part of the number characteristics, general for the minimum tensile strength. Such as: SS400 -- the first S Steel (Steel), the second S "Structure" (Structure), 400 for the lower tensile strength of 400 mpa, overall said ordinary Steel tensile strength of 400 mpa.
2, SPHC Steel Steel for - the first S, P is the abbreviation of Plate Plate, H is the abbreviation of hot Heat, C for Commercial ltd. abbreviation, said general with hot rolled Steel Plate and Steel belt as a whole.
3, SPHD -- said stamping with hot rolled steel plate and steel belt.
4, SPHE -- said deep drawing with hot rolled steel plate and steel belt.
(SPCC), 5 - said generally with cold-rolled carbon steel plate and steel belt, the equivalent of Q195-215 a brand in China. The third letter of the abbreviation of C for the Cold Cold. To ensure tensile test, at the end of the brand and T for SPCCT.
6, SPCD - said stamping with cold-rolled carbon steel plate and steel belt, the equivalent of China 08 al (GB/T13237-1991) of high quality carbon structural steel.
7, SPCE, said deep drawing with cold-rolled carbon steel plate and steel belt, equivalent to the Chinese SC1 (GB5213-2001) deep drawing steel. Need to ensure the timeliness, at the end of the number N for SPCEN. Cold rolled carbon steel sheet and strip steel conditioning code: annealing state for A, standard conditioning S, 1/8 hard for 8, 1/4 hard for hard to 2, 4, 1/2 to 1. Surface processing code: matt finishing for D, shiny finishing for B.
Such as (SPCC) - SD said standard conditioning, matt finishing of cold-rolled carbon is commonly used in sheet. Again such as SPCCT - SB said standard conditioning, light processing, guarantees of mechanical properties of cold rolled carbon sheet.
8, JIS method is: the mechanical structure with steel grades said S + carbon + letter (C, CK), the carbon content in the middle value by 100, said the letter "C" : said carbon K: case hardening steel. Such as carbon knot rolled plate S20C its carbon content is 0.18 0.23%.

Three, silicon steel sheet brand representation in China and Japan

1, the Chinese brand representation:
No orientation (1) cold rolling silicon steel belt (film)
Said method: DW + iron loss value (in the frequency of 50 hz, waveform for sinusoidal magnetic induction unit weight of the peak of 1.5 T iron loss value.) 100 times 100 times + thickness values. Such as DW470-50 said iron loss value of 4.7 w/kg, thickness of 0.5 mm cold rolled silicon steel without orientation, now represented by 50 w470 new model.
(2) the cold-rolled oriented silicon steel belt (film)
Said method: DQ + iron loss value (in the frequency of 50 hz, waveform for sinusoidal magnetic induction unit weight of the peak of 1.7 T iron loss value.) 100 times 100 times + thickness values. Sometimes add G said after the iron loss value high magnetic induction. Such as DQ133-30 said iron loss value is 1.33, the thickness of 0.3 mm cold rolled oriented silicon steel belt (film), is now said to 30 q133 new model.
(3) the hot rolled silicon steel plate
Hot rolled silicon steel plate with DR said, according to the silicon content of how much is divided into low silicon steel (silicon content of 2.8% or less), high silicon steel (silicon content > 2.8%). Said method: DR + iron loss value (magnetization and repeatedly with 50 hz by sinusoidal shape change of the magnetic induction intensity of a maximum of 1.5 T when the unit weight of the iron loss value) of the 100 times 100 times + thickness values. Such as DR510-50 indicates iron loss value of 5.1, the thickness of 0.5 mm hot rolled silicon steel plate. Home appliances with hot rolled silicon steel grades with JDR + value + thickness of metal loss, such as JDR540-50.
2, the Japanese brand representation:
(1) cold rolling without oriented silicon steel belt by the nominal thickness (100 times the value of the expand) code + A + iron loss guarantee value (will frequency 50 hz, the maximum magnetic flux density of 1.5 T when the iron loss value expand after 100 times). Such as thickness of 0.5 mm, 50 a470 said guarantee value for 4.7 or less metal loss of cold rolled silicon steel without orientation.
(2) the orientation of cold rolled silicon steel belt by the nominal thickness (100 times the value of the expand) + code G: said ordinary material, P: said high orientation material + iron loss guarantee value (will frequency 50 hz, the maximum magnetic flux density of 1.7 T when the iron loss value expand after 100 times). Such as thickness of 0.3 mm, 30 g130 said iron loss guarantee value orientation of cold rolled silicon steel belt for 1.3 or less.

Four, electrolytic tinplate and hot galvanized sheet

1, electrolytic tinplate
Tin plating steel sheet and strip, also known as tin, tin plating on the surface of the steel plate (with), has good corrosion resistance, non-toxic, can be used for packing material of canned, cable inside and outside to protect skin, telecom parts, flashlights and other hardware.
2, hot galvanized sheet
Hot galvanized sheet is divided into hot rolled steel sheet and hot galvanized steel sheet, cold rolled cold rolling hot galvanized sheet is mainly used for building
