Each department performs its own duties, unites and cooperates, and contributes its greatest strength to the overall operation of the company. So as to ensure the stable and sustainable development of the company.
Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to their different materials and properties. According to the different uses, A572 grade 55 high strength steel it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, welding gas cylinder steel and pressure vessel steel, pipeline steel, etc.
Special boiler steel is derived from carbon structural steel, A572 grade 55 high strength steel. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.
If the chromium content in A572 grade 55 high strength steel alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.

We have a stable system and professional human resource management work as the support, from the six aspects of guidance, cohesion, incentive, constraint, radiation and stability, we continue to introduce, modify and train employees from concept to action, and shape employees through constant guidance of common values.
The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
