What is the application scope of A588 Grade B railway steel

The company is a leading company that sells A588 Grade B railway steel steel plate products in the Central Plains region and has a high reputation in the steel plate industry. Since its establishment, the company has always adhered to the business philosophy of "integrity cooperation and common development", and has sold A588 Grade B railway steel steel products with various materials. The products are widely used in petroleum, chemical, construction, boiler, decoration, offshore operations, electric heating, gravity machinery and other industries.

Q345E steel plate is a low-alloy high-strength steel plate with good low-temperature impact performance. The steel grade is composed of three parts: Q (Qufu in Chinese spelling) representing yield strength, yield strength value, and quality grade symbol. A588 Grade B railway steel, Among them: Q represents the yield strength; 345 represents the yield strength value, unit MPa; E represents the grade (passed -40 degrees impact test).

The alloy layer of clad wear-resistant plate is mainly made of chromium carbide, and it is also equipped with molybdenum, niobium, titanium, boron and other components. The formation of multi-element carbides also has strong stability at high temperatures and can still be maintained below 500 °. High hardness and good oxidation resistance. The new clad wear-resistant plate A588 Grade B railway steelhas multiple performances of wear resistance, corrosion resistance, temperature resistance and impact resistance.

The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in A588 Grade B railway steel etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.

The tensile strength of A36 steel plate is 58-80 Ksi (about 400-550MPa), and the yield strength is 36 Ksi (about 250MPa); the tensile strength of Q235 steel plate is 370-500 MPa, and the yield strength is 235MPa; the tensile strength of SS400 steel plate is 400-510MPa, and the yield strength is 245MPa. For the mechanical properties of A588 Grade B railway steel, SS400 steel plate and Q235 steel plate, the thickness of steel plate is less than 16mm. It can be seen from the above data that ASME A36 and Chinese Q235 are named after the yield strength of the material, while SS400 is named after the tensile strength of the material.

It is a modern high-tech professional enterprise integrating scientific research, A588 Grade B railway steel production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as A588 Grade B railway steel process technology development, technology transfer and related technical consulting and technical services.
