Carbon structural steel plate
High-quality carbon structural steel is carbon steel with a carbon content of less than 0.8%. This steel contains less sulfur, phosphorus and non-metallic inclusions than carbon structural steel, and has better mechanical properties.
High-quality carbon structural steel can be divided into three categories according to the carbon content: low carbon steel (C≤0.25%), medium carbon steel (C is 0.25-0.6%) and high carbon steel (C>0.6%).
High-quality carbon structural steel is divided into two groups with normal manganese content (0.25%-0.8% manganese content) and higher manganese content (0.70%-1.20% manganese content) according to the manganese content. The latter has better mechanical properties. properties and processability.
1. High-quality carbon structural steel hot-rolled thin steel plate and steel strip
Steel plate knowledge High-quality carbon structural steel hot-rolled sheet and strip are used in the automotive, aviation industry and other sectors. The steel grades are boiling steel: 08F, 10F, 15F; killed steel: 08, 08AL, 10, 15, 20, 25, 30, 35, 40, 45, 50. 25 and below are low carbon steel plates, 30 and below Above 30 is a medium carbon steel plate.
2. High-quality carbon structural steel hot-rolled thick steel plate and wide steel strip
High-quality carbon structural steel hot-rolled thick steel plates and wide steel strips are used for various mechanical structural parts. The steel grades are low carbon steel including: 05F, 08F, 08, 10F, 10, 15F, 15, 20F, 20, 25, 20Mn, 25Mn, etc.; medium carbon steel includes: 30, 35, 40, 45, 50, 55, 60, 30Mn, 40Mn, 50Mn, 60Mn, etc.; high carbon steel includes: 65, 70, 65Mn, etc.
Special structural steel plate
1. Steel plates for pressure vessels: use a capital R at the end of the grade to indicate that the grade can be expressed by the yield point or by the carbon content or alloying elements. Such as: Q345R, Q345 is the yield point. Another example: 20R, 16MnR, 15MnVR, 15MnVNR, 8MnMoNbR, MnNiMoNbR, 15CrMoR, etc. are all represented by carbon content or alloy elements.
2. Steel plates for welding gas cylinders: use uppercase HP at the end of the grade to indicate, and the grade can be expressed by yield point, such as: Q295HP, Q345HP; it can also be expressed with alloy elements such as: 16MnREHP.
3. Boiler steel plate: use lowercase g at the end of the grade to indicate. Its grade can be expressed by yield point, such as: Q390g; it can also be expressed by carbon content or alloying elements, such as 20g, 22Mng, 15CrMog, 16Mng, 19Mng, 13MnNiCrMoNbg, 12Cr1MoVg, etc.
4. Steel plates for bridges: use lowercase q to indicate at the end of the grade, such as Q420q, 16Mnq, 14MnNbq, etc.
5. Steel plates for automobile beams: use capital L at the end of the grade to indicate, such as 09MnREL, 06TiL, 08TiL, 10TiL, 09SiVL, 16MnL, 16MnREL, etc.
Color coated steel plate
Color-coated steel sheets and strips are products based on metal strips and coated with various organic coatings on the surface. They are used in construction, household appliances, steel furniture, vehicles and other fields.

Structural steel for hull
Shipbuilding steel generally refers to steel for hull structure, which refers to the steel used to manufacture hull structures produced in accordance with the requirements of the classification society’s construction regulations. It is often used as a special steel for ordering, production scheduling and sales. A ship includes ship plates, section steel, etc.
