Comparison chart of S890 material equivalent structural

Q690E material has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance. In addition, S890 material equivalent, Q690 high strength steel plate and sheet has good corrosion resistance and certain wear resistance. High strength, especially in the normalizing or normalizing plus tempering state has a higher comprehensive mechanical properties.

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.

The main uses of flat steel are as follows. First, flat steel is used as a raw material for processing steel plates, which is convenient for transportation, takes up a small space, and can save transportation costs. Second, S890 material equivalent flat steel can be used as raw material for processing welded pipes. Flat steel can be a finished steel product, or it can be used as a billet for welded pipes and thin slabs for stacked sheets. Third, flat steel can be directly used as a steel structure. As a finished material, flat steel can be used for making hoop iron, tools and mechanical parts, and used as building frame structure and escalator in construction. Fourth, the flat steel has a smooth surface and a certain degree of beauty.

Steel is an alloy of iron with carbon, silicon, manganese, phosphorus, sulfur and a small amount of other elements. In addition to iron, carbon content plays an important role in the mechanical properties of S890 material equivalent and so on steel. Iron and steel is an important raw material for machinery, construction, hardware and other industries. As an important pillar industry, the development of iron and steel has a glorious period, in which Tangshan was once an important production base of China's iron and steel. This is closely related to its geographical location and energy advantages.
