BBNSTEEL low alloy steel A709 Gr 50 carbon steel plate sheet plant

Due to vast experience & concerted efforts of all employees, we are known as a reliable supplier of API 5l Line Pipe, seamless pipes and ERW pipes. Our A709 Gr 50 carbon steel plate sheet customers in the world has about 4000 clients in 70 countries such as Bangladesh, Saudi Arabia, Iran, Iraq, United Arab Emirates, Qatar, Bahrain, Oman, Kuwait, Turkey, Egypt, Jordan, Philippine, Singapore, Malaysia, Indonesia, Thailand, Vietnam, South Korea, Japan, Sri Lanka, Bangladesh, Argentina, Brazil, Colombia, Guyana, United States Of America, Canada, Mexico, Jamaica, Germany, France, Italy, United Kingdom, Spain, Netherlands, Belgium.

Our A709 Gr 50 carbon steel plate sheet pipeline steel has once again helped the construction of the China-Russia East Line Natural Gas Pipeline. During 2017 - 2018, the company successively supplied more than 10,000 tons of high-grade pipeline steel materials for the northern section of the Sino-Russian Eastern Gas Pipeline project, helping the northern section of the A709 Gr 50 carbon steel plate sheet project to be successfully completed. Now we reload the task and will provide API 5L X80 high-grade pipeline steel for the middle section of the China-Russia Eastern Gas Pipeline project.

The company's main steel plates have twelve types of steel products like boilers and pressure vessels, low-alloy high-strength steel A709 Gr 50 carbon steel plate sheet, wear-resistant steel plates, corrosion-resistant steel plates, high-rise building structural steel plates, marine structural steel plates, alloy structural steel plates, mold steel plates, carbon structural steel plates, shipbuilding and steel plates for oil production platforms, composite steel plates, steel plates for oil and gas pipelines. We offer various steel grades, and more than 300 kinds of thickness specifications.

After quenching and tempering, 40Cr alloy steel plate and A709 Gr 50 carbon steel plate sheet sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel A709 Gr 50 carbon steel plate sheet is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.

The company adheres to the needs of customers, adheres to win-win integrity, and relies on scientific and technological innovation to continue to improve the level of logistics equipment technology and information technology, and enhance the logistics technology research and development and innovation capabilities. Based on market demand and innovation as the driving force for development, the company actively expands the field of logistics services, accelerates the extension of the logistics industry chain, and scientifically advances the diversification of the logistics industry.
