What is the execution standard of dh36 ship steel plate

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of DH36 ship steel plate etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in dh36 ship steel plate etc. steel is strictly controlled.

Thin steel plate is a hot rolled or cold rolled steel plate with thickness between 0.2 and 4mm. The width of the thin steel plate is between 500 ~ 2500mm. According to different uses, dh36 ship steel plate sheet steel has different materials: ordinary carbon steel, high quality carbon structural steel, alloy structural steeldh36 ship steel plate, carbon tool steel, stainless steel, spring steel, electrical silicon steel and so on.

We specialize in the production and sale of steel products. We have many customers from all over the world. Our products dh36 ship steel plate have strict quality inspection departments, so we have absolute quality and technical advantages. Good promotion system, with advanced business philosophy, create development space, enhance the value of employees, improve the quality of life as the mission. Pursuing green procurement, energy conservation and consumption reduction.

What is the difference between CCS A and CCS B? Both CCS A and CCS B are structural steels for general strength hulls. The structural steel for hull is divided into four grades A, B, C and D according to quality. Steel plates belong to general strength plates, and the Mn content of chemical composition is very different, and there is no difference in mechanical properties, yield and tensile strength are the same. The difference is the experimental temperature of the impact energy, the A level is 20℃, and the B level is 0℃.
