What is the difference between carbon steel Q235B and S420ML hardness

The company initially focus on providing high-quality steel products to serve for China's rapid infrastructure development. Our company vision is to be the best service provider for iron & steel S420ML hardness products globally. To be an innovative business partner for our customers we aim to include sustainability in every aspect of our S420ML hardness business. We also provide third-party inspection and approval services and inventory management for our customers.

Common grades of carbon structural steel plates: A36, A283Grade C, A572Grade 60, A573Grade 70, Q235B, Q235C, S235JR, S275J0, SS400, St37-2, S420ML hardness, St52-3. Our company can provide carbon structural steel plate thickness ranging from 6 to 300mm. These plates are widely used in various types of engineering structures such as steel structure buildings, construction machinery, heavy vehicles, bridges, pressure vessels. Besides, we can provide Q235B carbon steel plate with Z direction test.

The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of S420ML hardness, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.

Temperature has a great influence on the strength of the material, S420ML hardness. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.

S420ML hardness, 12Cr1MoV steel is alloy structure steels, and it is usually produced into 12Cr1MoV steel coil, 12Cr1MoV steel sheet, 12Cr1MoV steel plate, 12Cr1MoV steel bar, etc. 12Cr1MoV steel is composed of Carbon, Silicon, Manganese, Chrome, Molybdenum and so on chemical elements. Amng them, the C content is 0.08-0.15, Si 0.17-0.37, Mn 0.40-0.70, Cr 0.90-1.20, Mo 0.25-0.35. The tensile strength of 12Cr1MoV steel is not lower than 490 Mpa, and yield strength is not lower than 245 Mpa.
