What is EN 10025 S460Q high strength steel equivalent steel in GB standard

As the basic processing materials and building materials, the medium and heavy plate is an important purchasing material for many manufacturers and construction enterprises, so the grasp of the latest price rise and fall of the medium and heavy plate, EN 10025 S460Q high strength steel is directly related to the cost and profit of enterprises. Therefore, it is necessary for purchasing staff to learn how to predict. Today, we share the latest price rise and fall skills, how to predict the price trend of medium and heavy plate, EN 10025 S460Q high strength steel.

S890 steel is a quenched and tempered high-strength steel plate, the series grades are S890Q, S890QL, S890QL1. S890Q, S890QL, S890QL1 steel,EN 10025 S460Q high strength steel plates, where S means structural steel, Q means that the impact temperature of the steel plate is -20°C, and QL means that the impact temperature of the steel plate is -50°C.
Then guess what QL1 stands for. QL1 means that the impact temperature of the steel plate is -60°C, and 890 means that the thickness is £50mm.

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 EN 10025 S460Q high strength steel and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.
