By purpose
(1) Bridge steel plate (2) boiler steel plate (3) Shipbuilding steel plate (4) Armor steel plate (5) Automobile steel plate (6) Roof steel plate (7) Structural steel plate (8) Electrical steel plate (silicon steel sheet) (9) Spring steel plate (10) Solar special plate (Hairuite steel) (11) Other two, common Japanese grades of steel plates for ordinary and mechanical structures.
Organized by steel grade
(1) Austenitic type (2) Austenite-ferrite type (3) Ferrite type (4) Martensitic type,
JIS
Japanese Steel (JIS series) in the grade of ordinary structural steel is mainly composed of three parts, the first part indicates the material, such as: S (Steel) indicates steel, F (Ferrum) indicates iron; The second part represents different shapes, types and uses, such as P (Plate) for plate, T (Tube) for tube, K (Kogu) for tool; The third part represents the characteristic number, which is generally the minimum tensile strength. For example: SS400 - the first S indicates Steel, the second S indicates "Structure", 400 is the lower limit tensile strength 400MPa, the overall tensile strength of 400MPa ordinary structural steel.
SPHC
SPHC - the first S is the abbreviation of Steel, P is the abbreviation of Plate plate, H is the abbreviation of Heat, C is the abbreviation of Commercial, the whole indicates the general use of hot rolled steel plate and steel strip.
SPHD
SPHD - stands for hot rolled steel sheet and strip for stamping.
SPHE
SPHE - stands for hot rolled steel sheet and strip for deep drawing.
SPCC
SPCC - denotes the general cold-rolled carbon steel sheet and steel strip, equivalent to the Q195A grade. The third letter C is short for Cold. To ensure the tensile test, add T to the end of the grade for SPCCT.
SPCD
SPCD - denotes cold-rolled carbon steel sheet and steel strip for stamping, equivalent to China's 08AL (13237) high-quality carbon structural steel.
SPCE
SPCE - stands for cold rolled carbon steel sheet and steel strip for deep drawing, equivalent to China 08AL (5213) deep drawing steel. To ensure timeliness, add N to the end of the brand for SPCEN. Tempering code of cold-rolled carbon steel sheet and steel strip: annealing state is A, standard tempering is S, 1/8 hard is 8, 1/4 hard is 4, 1/2 hard is 2, hard is 1. Surface processing code: dull finishing for D, bright finishing for B. SPCC-SD represents standard tempered, matte finishing carbon sheet for general cold-rolled. Another example is SPCCT-SB, which means the standard tempered and bright processing, requiring the cold-rolled carbon sheet to ensure the mechanical properties.
JIS mechanical structure is represented by the steel grade: S+ carbon content + letter code (C, CK), where the carbon content is expressed by the middle value ×100, and the letter C: indicates carbon K: indicates carburizing steel. For example, the carbon binding plate S20C has a carbon content of 0.18-0.23%. Third, China and Japan silicon steel sheet brand representation method.
Chinese brand
(1) Cold-rolled non-oriented silicon steel strip (sheet) expression method: DW+ iron loss value (at the frequency of 50HZ, waveform is sinusoidal magnetic induction peak value of 1.5T unit weight iron loss value.) 100 times the thickness + 100 times the thickness value. For example, DW470-50 means that the iron loss value is 4.7w/kg and the thickness is 0.5mm of cold-rolled non-oriented silicon steel, and the new model is 50W470.
(2) Cold-rolled oriented silicon steel strip (sheet) expression method: DQ+ iron loss value (at the frequency of 50HZ, waveform is sinusoidal magnetic induction peak value of 1.7T iron loss per unit weight.) 100 times the thickness + 100 times the thickness value. Sometimes G is added after the iron loss value to indicate high magnetic induction. For example, DQ133 represents a cold-rolled oriented silicon steel strip (sheet) with an iron loss of 1.33 and a thickness of 0.3mm, and the new model is 30Q133.
(3) Hot-rolled silicon steel plate Hot-rolled silicon steel plate is expressed by DR, and is divided into low silicon steel (silicon content ≤2.8%) and high silicon steel (silicon content > 2.8%) according to the silicon content. Expression method: DR+ iron loss value (50HZ repeated magnetization and sinusoidal variation of the maximum value of the iron loss per unit weight of 1.5T) + 100 times the thickness value. For example, DR510-50 indicates a hot-rolled silicon steel plate with an iron loss of 5.1 and a thickness of 0.5mm. The brand of hot-rolled silicon steel sheet for household appliances is expressed by JDR+ iron loss value + thickness value, such as JDR540-50.
Japanese brand
(1) The cold-rolled non-oriented silicon steel strip consists of nominal thickness (100 times the value of expansion) + code A+ iron loss guarantee value (the value of the iron loss when the frequency is 50HZ and the maximum magnetic flux density is 1.5T is expanded by 100 times). For example, 50A470 indicates a cold-rolled non-oriented silicon steel strip with a thickness of 0.5mm and an iron loss guarantee value of less than 4.7.
(2) The cold-rolled oriented silicon steel strip consists of nominal thickness (100 times the value of expansion) + code G: indicates the ordinary material, P: indicates the highly oriented material + the guaranteed value of iron loss (the value of expanding the iron loss value when the frequency is 50HZ and the maximum magnetic flux density is 1.7T by 100 times). For example, 30G130 indicates a cold-rolled oriented silicon steel strip with a thickness of 0.3mm and an iron loss guarantee value of ≤1.3. Liaocheng Suntory stainless steel provides four, electroplated tin plate and hot galvanized plate: 1, electroplated tin plate
Electroplated tin plate and steel strip, also known as tinplate, a kind of steel plate (strip) surface coated with tin, has good corrosion resistance, and non-toxic, can be used as packaging materials for cans, cable inside and outside protection, instrument telecommunications parts, flashlights and other hardware.
