Carbon steel top 5 factories in China

Q345E steel plate is a low-alloy high-strength steel plate with good low-temperature impact performance. The steel grade is composed of three parts: Q (Qufu in Chinese spelling) representing yield strength, yield strength value, and quality grade symbol. S690QL carbon equivalent, Among them: Q represents the yield strength; 345 represents the yield strength value, unit MPa; E represents the grade (passed -40 degrees impact test).

In today's S690QL carbon equivalent steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of S690QL carbon equivalent market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter S690QL carbon equivalent steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.

Weather-resistant steel is atmospheric corrosion-resistant steel. It is a low-alloy steel that has better corrosion resistance in the atmosphere than ordinary carbon steel by adding a small amount of alloy elements. Compared with S690QL carbon equivalent, weathering steel Q355NH, Q355GNHE weathering steel has better resistance to atmospheric corrosion. It is necessary to ensure that the steel plate has high strength and good plasticity and toughness. In addition, by adding a corrosion-resistant element to ensure the atmospheric corrosion resistance index I to reflect its good corrosion resistance.

With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel S690QL carbon equivalent product quality.
