At the same time, the company operates a variety of products of related iron and A573 Gr 70 hot selling carbon steel plate steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained A573 Gr 70 hot selling carbon steel plate ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.
A299GrA steel plate is one of the materials widely used in boiler drums (steam drums) of coal-fired generator sets. Boiler plate A573 Gr 70 hot selling carbon steel plate is mainly used in the head and shell of subcritical boiler drum products. Generally used for various welding parts whose working temperature does not exceed 400°C, such as boiler steam drums, pressure vessels, etc., which require the steel to have a high medium temperature.
Compared with carbon steel, alloy steel plate is a steel plate with other alloy elements added to the material, and the material performance is more excellent. Compared with other steel plates, alloy steel plates have outstanding performance. First, A573 Gr 70 hot selling carbon steel plate, alloy steel plate has higher strength, stronger bearing capacity, less breakage when bearing large objects, and longer service life. Second, alloy steel plate has good corrosion and wear resistance. In the open air environment, the steel selected for road and bridge paving must have high corrosion resistance and wear resistance, otherwise it will be damaged after a period of use and it will easily lead to accidents.
The effect of elements in the wear plate on high temperature temper brittleness: chromium, manganese, nickel, silicon, etc. play a role in promoting, while molybdenum, tungsten, titanium, etc. play a retarding role, and carbon also plays a role in promoting. Generally, A573 Gr 70 hot selling carbon steel plate, carbon wear-resistant steel plates are not sensitive to high temperature tempering brittleness, while binary or multi-element alloy steels containing chromium, manganese, nickel, and silicon are very sensitive. The degree of sensitivity varies depending on the type and content of alloy elements.
Chemical elements of 42SiMn steel: C: 0.39-0.45, Si: 1.10-1.40, Mn: 1.10-1.40. Mechanical properties of 42SiMn steel: tensile strength 885 MPa; yield strength 735 MPa; elongation after fracture: 15; reduction of area: 40; impact energy: 47J. 42SiMn steel belongs to alloy quenched and tempered steel with good properties, high strength, wear resistance and hardenability. Under certain conditions, the strength, wear resistance and hot working performance of 42SiMn steel are better than 40Cr steel, A573 Gr 70 hot selling carbon steel plate, and can be used instead of 40CrNi steel.
