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. A514 Gr P quenched and tempered steel, 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.
Wear resistant steel plate has high wear resistance and good impact performance. It can be cut, bent, welded, etc. Wear resistant steel plate can be connected with other structures by welding, plug welding, bolt connection, etc.. It is time-saving and convenient in the process of maintenance site. Wear resistant steel plate A514 Gr P quenched and tempered steel is widely used in metallurgy, coal, cement, power, glass, mining, building materials, brick and tile industries. Compared with other materials, it has a high cost performance and has been favored by more and more industries and manufacturers.
No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than A514 Gr P quenched and tempered steel. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel A514 Gr P quenched and tempered steel is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
