A514 grade E QT steel plate,ASTM A514 steel plate is a high yield strength, quenched and tempered alloy steel plate suitable for welding. A514 steel plate has high strength, and it can maintain mechanical properties even at very low temperature. At the same time, A514 steel plate also has good fatigue resistance, high toughness and low brittleness transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance.
Cold rolled coil products have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils with different surface roughness can be produced (glossy surface or matte surface, etc.).
The effect of alloy elements of Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.
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.
