20# steel plate is a high-quality low-carbon carbon steel plate, cold extruded, carburized and hardened steel. A514 grade B alloy steel plate, 20# steel has low strength, good toughness, plasticity and weldability The tensile strength is 253-500MPa, and the elongation is ≥24% 20# steel performance is basically similar to 15# steel, but the strength is slightly higher The cold-drawing or normalizing state of the cutting process is better than the annealing state 20# steel is used to manufacture various mechanical parts with high toughness under hot rolling or normalizing state, which require high toughness,A514 grade B alloy steel plate.

S355J2 steel plate belongs to European standard low alloy steel, the executive standard is EN10025-2. Delivery status: normalizing, hot rolling or control rolling. S355J2 corresponds to the Chinese Q345D, but the executive standard is different, the chemical composition is slightly different, but their mechanical properties are the same. S355J2 low alloy steel plate tensile strength (MPA): 450-680, impact value: - 20 ℃: ≥ 27J. S355J2 low alloy steel plate is widely used in bridges, vehicles, ships, buildings, steel structures, etc.
The microstructure of the quenched and tempered alloy steel after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.A514 grade B alloy steel plate
