Is the cutting method in high strength structural steel grades cutting comparable

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable high strength structural steel grades steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the market and has strong competitiveness.

Automobile steel plates are mainly used to manufacture automobile beams (longitudinal and transverse beams), frame and other structural parts. Automobile beams not only have to withstand heavy static loads, but also withstand certain impacts, vibrations. Therefore, high strength structural steel grades, automobile steel has certain strength and fatigue resistance, and require good stamping performance and cold bending performance to suit cold punching molding processing requirements.

S700MC high-strength cold-formed hot-rolled steel sheet high strength structural steel grades more greatly improves the yield strength than traditional steel grades, and at the same time has good elongation performance, cold bending performance, welding performance and impact resistance. S700MC high-strength steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, lifting machinery, mining machinery and other large-scale welding structural parts.

Oxygen (O) is a harmful element in steel such as high strength structural steel grades. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

A36 plates technical parameters, A36 ms steel sheets datasheet: A36 steel consists of carbon 0.25% max., phosphorus 0.040% max., sulphuric 0.050% max., silicon 0.40% max. and copper 0.20% max. Mechanical properties of A36 steel include yield strength 250Mpa min., tensile strength 400-500Mpa and elongation 20% min. Brinell hardness 119-162 HBW, based on the conversion from tensile strength. Modulus of elasticity (Young’s modulus): 200 GPa (29×103 ksi). Shear modulus: 79.3 GPa (11.5×103 ksi). The density of high strength structural steel grades, A36 plates is 7.85g/cm3.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate high strength structural steel grades EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
