The steel such as EN10025-4 S460ML steel supplier delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.
EN10025-4 S460ML steel supplier, Q460 material is a low-alloy high-strength steel. Q stands for the strength of steel. 460 means that plastic deformation occurs only when the strength of the steel reaches 460MPa. That is, when the external force is released, the steel can only maintain the shape of the force and cannot return to its original shape.This strength is greater than that of ordinary steel. Tensile strength is 550-720MPa, elongation: 17%, Q460 material is made by adding Cr, N, V, Ti and other alloying elements on the basis of 16Mn steel.
The tight supply of coal in Bohai Rim ports has eased, but high-calorie and low-sulfur coal is still in short supply; port resources are tight, traders are reluctant to sell at low prices, and the sentiment remains strong. Although the coal storage of key power plants is relatively high, the coal storage of coastal power plants is in the middle, and the enthusiasm for pulling transportation still exists. As the weather gradually turns colder, downstream power consumption increases, procurement demand continues to increase, and power plants release demand.
