The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing A514 Gr E structural steel material high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.
With the development of pipeline steel plate technology and the advancement of welded pipe forming and welding technology, the application scope of pipeline welded pipe is gradually expanding, especially in the range of large-diameter group spacing. Occupying a leading position in the field of line pipes has restricted the development of stainless steel seamless line pipes. In 2004, the output of A514 Gr E structural steel material seamless line pipes was about 400,000 tons, with steel grades including X42-70, and varieties of onshore line pipes and subsea line pipes.
Weathering steel plate A514 Gr E structural steel material for welding structure is made by adding chromium, molybdenum, titanium, vanadium and other metal materials into common steel liquid. Adding these materials can form a protective film on the surface, which can resist the corrosion of climate for a long time. Advantages: this kind of steel plate A514 Gr E structural steel material has excellent welding performance and weather resistance, and is widely used in railway, bridge and other areas requiring long-term exposure to the atmosphere.
Due to the existence of this dense oxide film, the infiltration of oxygen and water into the steel matrix in the atmosphere is prevented, the development of corrosion into steel material is slowed down, and the atmospheric corrosion resistance of steel material is greatly improved. A514 Gr E structural steel material, Weathering steel is a kind of steel system which can be used thinly, exposed or simply painted, and make products resistant to corrosion, prolong life, save labor and reduce consumption, upgrade and replace.
The carbon content of A514 Gr E structural steel material, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.
The company will rely on its good reputation, excellent hot-rolled plates, steel pipes, steel structure products, and intimate A514 Gr E structural steel material after-sales service to customers. I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! The company sincerely hopes to establish a long-term cooperative relationship with them, mutual benefit and common development. Welcome to come and visit our A514 Gr E structural steel material steel mill.
As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales.
