Pressure vessel steel plate is mainly used for manufacturing pressure vessel or other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure of astm a537 class 1 yield strength pressure vessel steel plate is 320kg / cm2 or 630kg / cm2 under normal pressure, and the temperature is within the range of - 20-450 ° C. It is required that the pressure vessel steel plate has not only certain strength and good plasticity and toughness, but also good cold bending and welding performance.

The Performance requirements of low alloy structural steel, astm a537 class 1 yield strength:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.

The primary purpose of adding alloy elements into steel is to improve the hardenability of steel and to ensure that martensite can be easily obtained during quenching. The second is to improve the tempering stability of the steel, to keep the martensite at a higher temperature, so that the carbide precipitated in the tempered steel is finer, uniform and stable. In this way, under the same conditions, astm a537 class 1 yield strength, alloy steel has higher strength than carbon steel. One of the main purposes of adding alloy elements is to improve the strength of steel.

astm a537 class 1 yield strength, S355J0 steel density is 7.85g/cm³. S355J0 density represents the mass per unit volume of S355J0 steel, which indirectly affects the price of S355J0 steel. Therefore, the density of S355J0 is also an important consideration for material selection. S355J0 steel tensile strength (σb / MPa):3
