Ordinary carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the steel, and generally does not add a lot of alloy elements. Ordinary carbon steel is the abbreviation of ordinary carbon structural steel. Carbon content is less than 0.38%, and less than 0.25% is the most commonly used. It belongs to low carbon steel. In the Chinese standard, each metal grade indicates the low yield point of the steel when the thickness is less than 16mm. Compared with high-quality carbon steel, the limitation of carbon content, performance range, phosphorus, sulfur and other residual elements is wider for ordinary carbon steel.SA709 Gr 50 carbon steel material

SA709 Gr 50 carbon steel material,With the fast development in Myanmar, Myanmar navy build frigate every year. We Cooperate with Myanmar Navy from 2015. They purchased 412 ton LR AH36 steel plate from us as trial order in 2015. After receiving the goods, they speak highly of the quality and our service. After that they purchase the shipbuilding steel plate from us regularly. In May,2018, the Myanmar navy’s local representative visit our office and production line, and sign another contract 2025 ton steel order in our office.

SA709 Gr 50 carbon steel material,Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.SA709 Gr 50 carbon steel material

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.
