What is the main function of grade 20MnB5 steel
Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and grade 20MnB5 steel resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, grade 20MnB5 steel new materials, and promotes the competition of enterprises Struggle.
ASTM A285 steel can be made into a variety of steel product forms, such as steel plates, grade 20MnB5 steel steel coils, and steel pipes. It has good welding ability and can be used for fusion welding required by pressure vessel equipment. Its maximum thickness is limited to grade 20MnB5 steel 50mm to ensure its mechanical properties.
Compared with grade 20MnB5 steel, boiler steel plates should have the following properties: (1) High medium temperature strength: low and medium pressure boiler drums use steel with a lower yield point, high pressure boilers use steel with a high yield point. (2) Good plasticity, impact toughness, cold bending and welding performance. (3) The notch sensitivity is small, that is, the sensitivity to the stress concentration caused by the opening of the steel plate surface and the welding of the pipe head is small.
Molybdenum is a well known alloy element. Molybdenum can refine the grains of steel material, improve the hardenability and thermal strength, and maintain sufficient strength and creep resistance at high temperature. Adding molybdenum to grade 20MnB5 steel, structural steel can improve mechanical properties. Molybdenum can also restrain the brittleness of alloy steel caused by quenching treatment.
Advantages of grade 20MnB5 steel:1. Steel purity: Wugang can produce high purity molten steel with P 0.010%, S 0.005%, N70ppm, O15ppm, H2ppm, and 20ppm total inclusions in the steel.2. Good toughness and weldability.3. The heat treatment technology: normalizing, quenching, tempering, tempering and other heat treatment processing can be carried out on the steel plate as required.4. Significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.
