Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for p295gh boiler steel inventory and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.

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 p295gh boiler steel inventory 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 p295gh boiler steel inventory 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.
