The company now has EN10149-2 S700MC hot rolled pickled t700 steel oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than EN10149-2 S700MC hot rolled pickled t700 steel 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

The yield strength of AH36, DH36, EN10149-2 S700MC hot rolled pickled t700 steel, EH36, and FH36 Steel for high-strength hull structure is not less than 355MPa, and the tensile strength is 490 ~ 620MPa. The letter A, D, E, and F indicate the impact toughness that they can achieve at 0°C, -20°C, -40°C and -60°C respectively. The yield strength of Grade AH40, DH40, EH40, FH40 hull structural steel is not less than 390MPa, the tensile strength is 510 ~ 660MPa.

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 EN10149-2 S700MC hot rolled pickled t700 steel, boiler tubes are also different. Generally speaking, boiler tubes must have pressure resistance, high temperature resistance, oxidation and corrosion resistance, and high tensile strength.

Composition characteristics of Q420 alloy steel plate: 1.Low carbon: Due to the high requirements for toughness, weldability and cold forming performance, its carbon content does not exceed 0.20%. 2. Add manganese-based alloy elements. 3. Add auxiliary elements such as niobium, titanium or vanadium, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the Q420 alloy steel, EN10149-2 S700MC hot rolled pickled t700 steel.
