The steel grades of thick steel plate are basically the same as those of thin steel plate. In terms of steel types, in addition to the bridge steel plate, boiler steel plate, automobile manufacturing steel plate, pressure vessel steel plate and multi-layer high-pressure vessel steel plate, some kinds of steel plates, such as automobile girder steel plate (2.5-10 mm thick), checkered steel plate (2.5-8 mm thick), stainless steel plate, heat-resistant steel plate, etc., are crossed with the thin plate.
Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <007% The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate has good processing performance Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low,A709 Gr HPS50W bridge steel plate.
Heat treatment is a very important process to improve the performance of metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the required structure and properties.A709 Gr HPS50W bridge steel plate
Mechanical properties of 45# steel high-quality carbon structural steel: Tensile strength σb (MPa): ≥600, yield strength σs (MPa): ≥355, elongation δ5 (%): ≥16, section shrinkage ψ (%): ≥40, impact energy Akv (J): ≥39. 45# steel impact toughness value αkv (J / cm2): ≥49 (5), hardness: unheated, ≤229HB; annealed steel, ≤197HB. 45# steel chemical composition % (Carbon: 0.42 to 0.50, Silicon: ≤0.40, Manganese: 0.50 to 0.80, Sulfur: ≤0.045, Phosphorus: ≤0.045, Chromium: ≤0.40, Nickel: ≤0.40, Molybdenum: ≤0.10).
We have a professional production team and high-quality production equipment, and we also have a great advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the production of high-quality steel plates, steel pipes and other products that meet customer requirements.A709 Gr HPS50W bridge steel plate
