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 steel plate grade AH32 and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
Common ship steel plates: A, B, D, E. The upper yield strength is greater than 235MPa. Grades B, D, E indicate the impact resistance of low temperature resistance at 20℃, -20℃, -40℃. The A-class ship plate in the ship plate is closer to Q235A The Class B ship plate in the ship plate is closer to Q235B.

According to foreign media reports, despite the impact of the coronavirus epidemic, most German screw steel plate grade ah32 steel producers still maintain a good level of production. This is in sharp contrast to the situation in other European countries and Germany's domestic steel mills, which are suffering from a slowdown due to the spread of the epidemic. Lotter kummatt Stahl, a local distributor, told customers on its website: "there is no reason at present to believe that German steel mills such as Riva and ferralpi are no longer able to serve the steel plate grade ah32 market due to the impact of the closure of local steel mills in Italy.
