High quality hardox 400 equivalent application and usage
BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of HARDOX 400 equivalent steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main HARDOX 400 equivalent production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.
Precautions for procurement of HARDOX 400 equivalent, corrosion resistant steel. First, thickness. According to the thickness, corrosion-resistant steel can be divided into thin plate, medium plate, thick plate and extra thick plate, and each thickness has different application fields. Second, the choice of length and width, which can be cut to required size. Third, standards, each country has its own standards, so when purchasing corrosion resistant steel, it depends on which country it is used. Fourth, it is better to let professionals to purchase HARDOX 400 equivalent or corrosion resistant steel.
Ordinary carbon steel killed steel plate deoxidizes the liquid steel before making. When the liquid steel is poured into the ingot, its reaction is relatively calm and there is no boiling state. Advantages: this kind of steel plate HARDOX 400 equivalent has no gas, less impurities, uniform stress and good welding performance. Widely used in demanding parts
Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while HARDOX 400 equivalent steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of HARDOX 400 equivalent steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
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, HARDOX 400 equivalent. 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.
Respect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise. Adhere to this concept, so that the service and the product are the same, long-term.
