| Surface treatment | Features and Uses |
| 2B | The surface brightness and flatness of No.2b is better than that of 2D. And then a special surface treatment to improve its mechanical properties. No. 2B can be used for almost all purposes. |
| No.1 | It is polished with 100-200 matte belt, with good gloss and discontinuous coarse grain. It is used for interior and exterior decoration of buildings, electrical appliances and kitchenware. |
| No.4 | Polishing with 150-180 matte belt, with better brightness and discontinuous coarse grain, but thinner than no.3, used for bathtub, building interior and exterior decoration, electrical appliances, kitchenware, food processing equipment, etc |
| HL | Surface 4 is polished with 150-320 sand belt and has continuous stripes. It is mainly used for building decoration elevators, building door panels, front panels and so on. |
| 8K | This product has excellent brightness and excellent reflectance, can be used as a mirror |
| 8A | Products after cold rolling bright annealing, skin treatment, with good gloss and reflectance, suitable for mirrors, kitchenware, decorations and so on. |
Steel is an iron-carbon alloy with carbon content between 0.04% and 2.3%. In order to ensure its toughness and plasticity, the carbon content is generally not more than 1.7%. In addition to iron and carbon, the main elements of steel are silicon, manganese, sulfur and phosphorus. There are a variety of steel classification methods, the main methods are as follows:
1. Classification by quality
(1) Ordinary steel (P≤0.045%, S≤0.050%)
(2) High quality steel (P, S ≤0.035%)
(3) High quality steel (P≤0.035%, S≤0.030%)
2. Classification according to chemical composition
(1) Carbon steel: low carbon steel (C≤0.25%); Medium carbon steel (C≤0.25-0.60%); High carbon steel (C≤0.60%).
(2) Alloy steel: low alloy steel (total alloying element content ≤5%); Medium alloy steel (total alloying element content > 5-10%); High alloy steel (total alloying element content > 10%).
3, according to forming method classification:
(1) forging steel
(2) cast steel
(3) the hot rolled steel
(4) Cold drawn steel.
4. Classification according to metallographic organization
(1) annealing state: hypoeutectoid steel (ferrite + pearlite); Eutectoid steel (pearlite); Eutectoid steel (pearlite + cementite); Lastenitic steel (pearlite + cementite).
(2) normalizing: pearlite steel; Bainitic steel; Martensitic steel; Austenitic steel.
(3) having no or partial phase transition
5. Classification by use
(1) Construction and engineering steel: common carbon structural steel; Low alloy structural steel; Reinforced steel.
(2) structural steel
A. Mechanical steel: tempered and tempered structural steel; Surface hardening structural steel: including carbon steel, ammonia steel, surface hardening steel; Shear structural steel; Steel for cold plastic forming: including steel for cold stamping and steel for cold heading.
B. spring steel
C. bearing steel
(3) tool steel: carbon tool steel; Alloy tool steel; High speed tool steel.
(4) Special performance steel: stainless acid resistant steel; Heat resistant steel: including oxidation resistant steel, heat strength steel, valve steel; Electrothermal alloy steel; Wear resistant steel; Low temperature steel; Electrical steel.
(5) Professional steel: such as bridge steel, ship steel, boiler steel, pressure vessel steel, agricultural machinery steel, etc.
6. Comprehensive classification
(1) ordinary steel
A. Carbon structural steel: Q195; Q215 (A, B); Q235(A, B, C); Q255 (A, B); Q275.
B. Low alloy structural steel
C. Ordinary structural steels for specific purposes
(2) High quality steel (including high quality steel)
A. Structural steel: high quality carbon structural steel; Alloy structural steel; Spring steel. Free cutting steel. Bearing steel. High quality structural steel for specific purposes.
B. Tool steel: carbon tool steel; Alloy tool steel; High speed tool steel.
C. Special performance steel: stainless acid resistant steel; Heat resistant steel; Electrothermal alloy steel; Electrical steel; High manganese wear resistant steel.
7. Classification by smelting method
(1) according to furnace type
A. Open hearth steel: acid open hearth steel; Basic open hearth steel.
B. Bessemer steel: acid Bessemer steel; Basic Bessemer steel. Or bottom blown Bessemer steel; Side blown bof steel; Bof steel.
C. Electric furnace steel: arc furnace steel; Electroslag furnace steel; Induction furnace steel; Vacuum consumable furnace steel; Electron beam furnace steel.
