The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable astm a573 grade 58 high strength structural steel sheet steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the market and has strong competitiveness.
EN 10083/3-2006 42crmo4 is an industrial material. 42CrMo4 is used to manufacture forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods and spring clips that are heavily loaded. 42CrMo4 is also It can be used for oil deep well drill pipe joints and fishing tools under 2000m.
High-temperature boiler steel plates such as 15CrMoR plate, 12Cr1MoVR steel plate, ASME SA387 grade 22 steel, A387 Gr 91 boiler steel, ASME SA1017 Gr 23, SA1017 Gr 911, SA1017 Gr 122 steel, astm a573 grade 58 high strength structural steel sheet, must have features of:Sufficient high temperature durability and durable plasticity;Good high temperature tissue stability;Good high temperature oxidation resistance (heat resistance);Good hot and cold processing technology (mainly refers to cold bending deformation and weldability), etc.
Oxygen (O) is a harmful element in steel such as astm a573 grade 58 high strength structural steel sheet. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.
Difference between Q235A steel and Q235B steel plates: in the national standard GB700, the difference between astm a573 grade 58 high strength structural steel sheet, Q235A steel and Q235B steel plates is mainly in the carbon content. In addition, Q235A steel plate does not do impact test, while Q235B Q235B steel plates need normal temperature impact test, V-notch. Relatively speaking, the mechanical properties of Q235B steel plates are better than that of Q235A steel plate.
Our company has strict quality control standards. If you want to visit our factory, you are welcome at any time! We produce a lot of steel products every month to export astm a573 grade 58 high strength structural steel sheet to all over the world. Because our customers are from all countries, they will order a large number of steel products from our company every month.
