Based on the advantages of A514 grade B quenched and tempered steel steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel A514 grade B quenched and tempered steel products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .
The company manages NM400 wear-resistant plate, NM450 wear-resistant plate, A514 grade B quenched and tempered steel, NM500 wear-resistant plate and other wear-resistant plate products. The wear-resistant plates are widely used in many industries, such as engineering, mining, cement, power, construction, machinery, coal, glass manufacturing, paper making, metallurgy, petrochemical, etc.. And the wear-resistant plates are also used in wheel device, grab equipment, bucket body, edge, lining plate, hopper, funnel, bucket valve, etc. parts.
The excellent properties of wear resistant steel plate meet the strict requirements of high strength, high wear resistance, stability, straightness and surface quality. The combination of high hardness, high strength and excellent impact toughness makes A514 grade B quenched and tempered steel plate become an ideal material for a wide range of applications. The production thickness of wear resistant steel plate is generally between 8-100mm.
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 grade B quenched and tempered steel, 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.

We are leading supplier of pipeline steel. The pipeline steel in usually in forms of pipeline steel coils, pipeline steel sheet, pipeline steel plate and pipeline steel pipes. And the most popular standard is API 5L. For questions about A514 grade B quenched and tempered steel pipeline steel, such as X70 steel properties, API 5L X42 steel properties, difference between API 5L PSL1 and API 5L PSL2, API 5L grade B steel price, please feel free to communicate with us.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
