The company initially focus on providing high-quality steel products to serve for China's rapid infrastructure development. Our company vision is to be the best service provider for iron & steel A514 Gr E QT steel plate products globally. To be an innovative business partner for our customers we aim to include sustainability in every aspect of our A514 Gr E QT steel plate business. We also provide third-party inspection and approval services and inventory management for our customers.
SA516 Gr65 sheet is a carbon steel plate for medium and low temperature pressure vessels. It implements the ASME standard of the American Standard. It can provide a minimum thickness of 8mm and a width of 1500~4000mm. The A514 Gr E QT steel plate product thickness direction (Z-direction) resistance to tearing and wet hydrogen sulfide corrosion can be added Performance (HIC+SSCC) steel. Steel used to manufacture pressure vessels for petrochemical, gas separation and gas storage and transportation equipment.
Our SA516Gr70 pressure vessel plate has good impact resistance, small temperature deformation, good welding performance, good fatigue resistance, good anti-layered cracking performance, micro-alloying, high purity, low carbon equivalent, strong resistance to sulfur and hydrogen. The product has good dimensional tolerance and surface quality. China made A514 Gr E QT steel plate steel plates are now widely used in major chemical sites.
The composition characteristics of low alloy high strength steel are low carbon ≤0.20%, low alloy, and total alloying elements is less than 3%. The low carbon content is to meet the process performance requirements of A514 Gr E QT steel plate, low alloy high strength steel for engineering structural parts such as plasticity, toughness, weldability and cold deformation; adding a small amount of alloying elements (mainly Mn) to achieve the purpose of improving mechanical properties. Mn not only has a significant strengthening effect on ferrite, it can also reduce the cold brittle temperature of steel, increase the amount of pearlite in the steel, and further improve the strength.
A514 Gr E QT steel plate, No. 20 steel belongs to high-quality carbon steel.No. 20 steel means steel with an average carbon content of 0.20%;The thermal conductivity of No. 20 steel at 315℃ is 48 W/m℃;No. 20 steel is generally not quenched, the general treatment method is carburizing or normalizing;The yield strength of No. 20 steel is not less than 250MPa;The tensile strength of No. 20 steel is not less than 420MPa;Elongation of No. 20 steel is not less than 25%;The reduction of area is not less than 55%;The density of A514 Gr E QT steel plate and No. 20 steel is 7.85kg/cm3
Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s A514 Gr E QT steel plate domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.
If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
