How much is A588 Grade B tempered and quenched steel cost per square foot

Steel is the main raw material for shipbuilding and marine engineering structure construction, accounting for 20% ~ 30% of the construction cost of hull and marine engineering. The steel A588 Grade B tempered and quenched steel products involved mainly include steel plates and section steel (marine bulb flat steel, H-beam, angle steel, etc.), casting and forging steel and supporting welding materials, etc. Among them, the amount of steel consumed for hull construction accounts for about 60% of the total ship mass, and sheet metal accounts for about 88%.

A588 Grade B tempered and quenched steel, 20CrMo alloy steel plate has high hardenability, no temper brittleness, good weldability, little tendency of cold cracking, good machinability and cold strain plasticity. 20CrMo alloy steel plate is generally used in the state of quenching and tempering or carburizing and quenching. 20CrMo alloy steel plate is used to manufacture high-pressure pipes, fasteners and carburized parts, such as gears and shafts, working in non corrosive medium and medium containing mixture of nitrogen and hydrogen under 250 ℃.

The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for A588 Grade B tempered and quenched steel pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common A588 Grade B tempered and quenched steel carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.
