What is the most important characteristic of 30MnB5 alloy steel for turbine part

The company has allocated special environmental protection facilities for all 30MnB5 alloy steel for turbine part pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, 30MnB5 alloy steel for turbine part steel mill scale, environmental protection dust has reached 100%.

Chinese grade of 20# steel plate: No.20American grade: ASTM1020Japanese grade: S20CGerman, British and French grades: C22, C20CMaterial No.: 1.0402, 1.0411Density: 7.85The strength of 20# steel plate is slightly higher than that of 15# steel plate, with little quenching and no tempering brittleness. 30MnB5 alloy steel for turbine part, 20# steel plate is generally used for bending and so on processing. The welding performance of arc welding and contact welding is good. When gas welding, the 20# steel plate with thin thickness and strict or complex shape is easy to crack.

Q345R steel plate is a special pressure vessel steel with a yield strength of 340 Mpa. 30MnB5 alloy steel for turbine part, Q345R pressure vessel steel has good comprehensive mechanical and technological properties. The content of phosphorus and sulfur of Q345R pressure vessel steel is slightly lower than that of Q345 (16Mn) steel, and the tensile strength and elongation requirements of Q345R pressure vessel steel are higher than those of Q345 (16Mn) steel, and the impact toughness of Q345R pressure vessel steel is also required. Q345R pressure vessel steel is the most widely used Chinese pressure vessel steel.

Large-thickness 30MnB5 alloy steel for turbine part, Z35 grade steel plate is a kind of extra-thick steel plate that is applied under specific environmental conditions, such as the key parts such as the turbine seat ring and guide vane of the generator set. It has high requirements for safety, reliability, and long service life. Develop 200mm-300mm thick steel plate of Z35 level, to ensure that the layer tear resistance reaches Z35 level. 300mm thick Z35 grade steel plate can be used not only in the hydropower industry, but also in the manufacture of other large key equipment, and has broad prospects.
