Characteristics of A302GrB steel plate

A302GrB container steel plate bears different pressure and strength due to the manufactured container. Generally, the normal pressure is 314MPa or higher, and the working temperature is often between -20°C-450°C, and sometimes lower than -20°C. According to the working conditions and processing technology requirements of the container, the A302GrB steel plate must have good cold bending and welding performance, good plasticity and toughness, and high-temperature short-term strength or long-term strength. In addition to high-quality carbon steel, low-alloy structural steel is mostly used as material at present.

A302MGrB steel plate itself has high strength, high toughness, corrosion resistance, impact resistance and weldability. A302MGrB steel plate is often used in the boiler and petrochemical equipment manufacturing industry, such as petrochemical equipment, petroleum equipment, steam turbines, hydropower station equipment, pressure pipes, heads, pressure components and other export machinery and equipment.
