We are mainly engaged in corrosion-resistant steel materials and steel processing parts, the varieties include ASTM A709 structural steel sheet Q355NHB, Q345NS, 09CuPCrNi-A,coten-A/B,S355J0W, Q345qNHB. The application fields involve landscape gardening, outdoor structure, environmental protection equipment, railway carriage, bridge manufacturing and many other industries. The company currently has many steel extension processing capabilities such as laser cutting, bending, rolling, welding, pipe making, and surface treatment.
The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating ASTM A709 structural steel sheet production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.
Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of ASTM A709 structural steel sheet, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.
Compared with the common pressure vessel, the pressure parts of the boiler not only bear the pressure, but also suffer from the radiation and erosion of the high temperature flue gas. Once the pressure components of the boiler fail in operation, it will cause extremely serious consequences. Therefore, the ASTM A709 structural steel sheet, steel materials used to manufacture the pressure components of the boiler must have enough high strength, plasticity, toughness, fatigue resistance and corrosion resistance, as well as good high-temperature mechanical properties for high-temperature components.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel ASTM A709 structural steel sheet plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
