The company adheres to the core values of "quality and benefit, integrity and win-win, innovation and efficiency", and provides first-class services. Based on the principle of reputation first, small profits and high sales, we develop the market with high-quality services and flexible business model.
Medium and thick plates sa573gr.70 chemical composition are mostly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction, etc. Medium and thick plates can also be used to make all kinds of containers, furnace shells, furnace plates, automobile static steel plates and so on. Among them, shipbuilding steel plate is used to make marine and inland ships. The shipbuilding steel plate sa573gr.70 chemical composition is required to have high strength, plasticity, toughness, good cold bending performance, welding performance and corrosion resistance.
Alloy spring steel is a kind of steel which can improve the mechanical properties, hardenability and other properties of the steel by adding some alloy on the basis of carbon steel to meet the requirements of manufacturing various springs. Its advantages are that it integrates other materials, making spring more stable, durable, long life. sa573gr.70 chemical composition, Alloy spring steel has high elastic limit, high yield ratio, high fatigue strength and enough toughness.
For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In sa573gr.70 chemical composition, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.
20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, sa573gr.70 chemical composition. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.
The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality sa573gr.70 chemical composition products and excellent services. Our company's products sa573gr.70 chemical composition are widely used in petroleum, chemical, power station, boiler and other industries, mainly used in reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear energy reactor pressure shells and other equipment.
Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, sa573gr.70 chemical composition sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding.
