Since the beginning of this year, the global asme sa572 grade 50 mechanical properties steel pipe industry, like many other industries, is facing severe market situation. The difference is that novel coronavirus pneumonia is not only affected by the epidemic, but also closely linked to the oil and gas industry, and the global asme sa572 grade 50 mechanical properties steel tube industry will also suffer from the "flash collapse" of international oil prices in March.
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 asme sa572 grade 50 mechanical properties and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
