Our company was founded in 2000, which initially committed to providing high-quality steel ASTM A588 high strength steel products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export ASTM A588 high strength steel steel to the international market, opening up the international steel market.
The diameter of large diameter seamless steel pipe is 325mm-1220mm, and the maximum thickness that can be achieved is 200 mm. The diameter of small diameter seamless steel pipe is generally less than 89mm. The processing technology of large diameter seamless steel pipe is hot rolling or hot expanding. There are many materials for large diameter seamless steel pipe, such as ASTM A588 high strength steel, which can be processed and customized according to customer requirements. The large diameter seamless steel pipe is usually used in the chemical, petroleum, mechanical and other industries.
The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with ASTM A588 high strength steel, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.
Our strutural steel plates are not attacked easily by the chemicals in harsh weather. They are a hard, strong, and durable product. Their characteristics are tested through tests. We perform hardness, pmi, micro, chemical, mechanical, macro, ultrasonic test and more. We pack carbon steel plates, ASTM A588 high strength steel, hot rolled plates, structural steel sheets safely to maintain their good performance so that they serve longer than usual.
Pressure vessel steel plates are mainly used for manufacturing pressure vessels and other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure of pressure vessel steel plates ranges from normal pressure to 320kg / cm2 or even 630kg / cm2, and the temperature ranges from - 20 °C to 450 °C. In addition to certain strength, good plasticity and toughness, pressure vessel steel plates must also have good cold bending and welding properties. Q245R, Q345R, 14Cr1MoR, 15CrMoR, ASTM A588 high strength steel etc. are common pressure vessel steel grades.
As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another ASTM A588 high strength steel magnificent projects.
Since its establishment, the company has been deeply supported and loved by customers with its unique business philosophy and business model. The company has always adhered to the tenet of "credibility first, integrity-based, quality first" and sincerely serves new and old customers. At the same time, it keeps pace with the times based on market orientation, continuously expands offline channels, and gradually establishes a complete online E-commerce business management platform. We will always promote our after-sales service to make client satisfied with our goods.
