Iron and steel goods, including pig iron, ingots, all kinds of steel and so on. Therefore, logistics companies are required to load evenly and evenly in the process of transportation, prevent moisture and prevent corrosion. It is necessary to prevent the A709 Gr 50S bridge steel plate steel sheet from being mixed with water when transporting the steel; it is necessary to prevent the A709 Gr 50S bridge steel plate steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when loading the A709 Gr 50S bridge steel plate steel sheet on the truck Good luck.
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 A709 Gr 50S bridge steel plate and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the A709 Gr 50S bridge steel plate metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between A709 Gr 50S bridge steel plate strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
