According to the type of production, boiler tubes can be divided into seamless steel tubes and welded steel tubes. Boiler tubes are mainly used in pipelines, heating equipment, machinery industry, petroleum geological exploration, chemical industry and other fields. Because of the special purpose of the boiler tubes, the technical parameter requirements of the SMA490CW hot rolled plate for construction machinery, boiler tubes are also different. Generally speaking, boiler tubes must have pressure resistance, high temperature resistance, oxidation and corrosion resistance, and high tensile strength.

The purpose of SMA490CW hot rolled plate for construction machinery quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of SMA490CW hot rolled plate for construction machinery. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.

The Indian customer purchased our A516 Gr 70 pressure vessel steel plates to make tanks. They have very strict requirement for raw materials quality. For the A516 Gr 70 pressure vessel steel plates, they asked for Normalizing, 0℃ impact, A578 UT test, PWHT and so on tests, our Q/C department witness the production process with the technician from the customer company together. Meanwhile, we arrange BV inspection to check the quantity, spray mark, stamp on the A516 Gr 70 pressure vessel steel plates, and so on.
