Stainless steel plate manufacturing method are two hot and cold, including sheets and 4.5-35 mm thickness of 0.5-4 mm thick plate, according to organizational characteristics of steel divided into five categories: austenitic, austenitic Body - ferritic, ferritic, martensitic, precipitation hardening. Requirements can withstand acid, sulfuric acid - ferric sulfate, nitrate, nitric acid - hydrofluoric acid, sulfuric acid - copper sulfate, phosphoric acid, formic acid, acetic acid and other corrosive, widely used in chemical, food, pharmaceutical, paper, oil, nuclear, etc. industry and construction, kitchen utensils, cutlery, vehicles, household appliances all kinds of parts. In order to ensure the yield strength of stainless steel plates, the mechanical properties of tensile strength, elongation and hardness to meet the requirements, you must go through annealing, solution heat treatment, aging heat treatment before delivery plate. Corrosion resistance of stainless steel primarily depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal organizational structure, play a major role in the chromium. Chromium has a high chemical stability, can form a passive film on the steel surface, the metal with the outside world to isolate and protect steel from oxidation and increase the corrosion resistance of steel. After the destruction of the passive film, corrosion resistance on the decline. Category 3: Classification according to the thickness (1) sheet (2) in the plate (3) Plate (4) special plate classification according to production method (1) hot-rolled steel (2) cold-rolled steel by the surface characteristics of classification (1) Plating zinc plate (hot galvanized plate, galvanized sheet) (2) tin plate (3) composite plate (4) color coated steel by use classification (1) bridge steel plate (2) boiler plate (3) shipbuilding steel plate (4 ) armor plate (5) automotive steel (6) roof plate (7) Structural Steel (8) electrical steel (silicon) (9) of the spring plate (10) the other two, ordinary and common mechanical structure with steel grade JIS in Japan Series 1, Japanese steel (JIS series) grades of ordinary structural steel is mainly composed of three parts of the first portion indicates material composition, such as: S (Steel) represented steel, F (Ferrum) represents iron; the second part represents the different shapes, kinds , uses, such as P (Plate), said plate, T (Tube), said tube, K (Kogu) expressed tools; Part III features a digital representation, usually a minimum tensile strength. Such as: SS400-- first S represents steel (Steel), S represents a second "structural" (Structure), 400 for the lower limit of the tensile strength of 400MPa, a tensile strength of the whole expressed 400MPa of ordinary structural steel. SPHC 2, SPHC-- first steel Steel abbreviation S, P is the abbreviation plate Plate, H for Hot Heat abbreviation, C abbreviation for Commercial Commercial, said the general overall hot-rolled steel sheet and strip. SPHD 3, SPHD-- expressed stamping hot-rolled steel sheet and strip. SPHE 4, SPHE-- expressed deep drawing hot-rolled steel sheet and strip. SPCC 5, SPCC-- expressed general cold rolled carbon steel sheet and strip, which is equivalent in Q195-215A grades. Where C is the third letter abbreviation Cold Cold. When the need to ensure the tensile test at the end of grades plus T for SPCCT. SPCD 6, SPCD-- expressed drawing cold rolled carbon steel sheet and strip, equivalent to Chinese 08AL (13237) quality carbon structural steel. SPCE 7, SPCE-- expressed deep drawing cold rolled carbon steel sheet and strip, equivalent to Chinese 08AL (5213) deep drawing steel. The need to ensure non-aging property, the N is added at the end of grade SPCEN. Cold-rolled carbon steel sheet and strip quenching Code: annealed state A, the standard quenching of S, 1/8 hard for 8,1 / 4 hard for 4,1 / 2 hard 2 hard one. Surface processing code: Matte finish is D, bright finish for B. SPCC-SD represents the standard quenched, usually with a matte finish of cold-rolled carbon sheet. Again SPCCT-SB represents the standard conditioning, light processing, cold-rolled carbon sheet to ensure that the requirements of the mechanical properties. 8, JIS mechanical structural steel grades that method: S + carbon content + letter code (C, CK), in which the carbon content of intermediate value × 100, said the letter C: carbon K: represents carburizing steel. S20C carbon structural steel coil as its carbon content of 0.18-0.23%. 4 Representation China Grade: (1) cold-rolled non-oriented silicon steel strip (sheet) representation: (at a frequency of 50HZ, sinusoidal waveform peak magnetic induction unit weight of iron loss 1.5T) DW + iron loss 100x + 100 times thickness values. Iron loss is expressed as DW470-50 4.7w / kg, thickness of 0.5mm cold-rolled non-oriented silicon steel, is the new model is represented as 50W470. (2) cold rolled grain oriented silicon steel strip (sheet) representation: DQ + iron loss value (at a frequency of 50HZ, sinusoidal waveform peak magnetic induction unit weight of iron loss 1.7T) 100 100 times + thickness values times. Sometimes after the iron loss value plus G represents a high magnetic induction. DQ133-30 iron loss is expressed as 1.33, thickness of 0.3mm cold rolled grain oriented silicon steel strip (sheet), the new model is now represented as 30Q133. (3) hot-rolled silicon steel sheet hot-rolled silicon steel sheet with DR said, according to the number of silicon content into low silicon (silicon content ≤2.8%), high-silicon (silicon content> 2.8%). Representation: DR + iron loss (with 50HZ repeatedly magnetized and by sinusoidal variation of the maximum magnetic flux density per unit weight of the iron loss when 1.5T) + 100 times 100 times thickness values. As DR510-50 iron loss value of 5.1 indicates a thickness of 0.5mm hot rolled silicon steel sheet. Household appliances, hot-rolled silicon steel sheet with a grade of iron loss by JDR + value + thickness value expressed as JDR540-50. Japanese Grade: (1) cold-rolled non-oriented silicon steel strip by the nominal thickness (expanded 100-fold value) + code A + iron loss guaranteed (will expand to 100 times the frequency of 50HZ, maximum flux density of the iron loss at 1.5T after value). 50A470 expressed as thickness of 0.5mm, the iron loss guarantee value ≤ 4.7 cold rolled non-oriented silicon steel strip. (2) cold-rolled silicon steel strip by the nominal thickness (enlarged 100 times the value) + code. G: common materials, P: represents highly oriented material + iron loss guarantee value (frequency 50HZ, maximum flux density of 1.7T measurements of the iron loss value after 100 times enlarged). 30G130 expressed as thickness of 0.3mm, the iron loss assure cold rolled grain oriented silicon steel with a value of ≤1.3.
