3m X 6m X 150mm SM520C material equivalent standards Plate
With high-quality SM520C material equivalent standards steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our SM520C material equivalent standards steel market and improved the control of steel plate production quality.
Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, SM520C material equivalent standards included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.
S420NL-Z35 steel plate is alloy structural steel, and it implements the European standard EN 10025-3. The chemical composition of S420NL-Z35 steel plate: C:≤0.2, Si:≤0.6, Mn: 1 - 1.7, P:≤0.025, S:≤0.02. Delivery state of SM520C material equivalent standards, S420NL-Z35 steel plate: quenching + tempering. Of course, the delivery status can also be selected according to specific demands. However, it needs to be communicated between the supplier and the demander and indicated in the contract.
The unloading of Australian coal has ceased, and the quota for imported coal has been reduced. The domestic coal supply gap has gradually emerged. In the case of high inventories of power plants, there are hidden concerns about subsequent coal transfer channels. At present, there has been an increase in the number of ships that have completed the formalities of anchoring ships at Qin Port and Huanghua Port, indicating that a new round of procurement will kick off, prompting traders to continue to raise prices.
