Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and A709 Gr 50 carbon steel plate heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported A709 Gr 50 carbon steel plate to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
ASTM A335 P11, P22, P91 pipes are commonly used in power plants and chemical-petrochemical industry, while P9 and P5 pipes are mainly used in petroleum refineries. BBN steel company supplies ASTM A335 Cr-Mo alloy steel seamless pipes sized from 1/2″ to 24″ranging in wall thickness from SCH20 to XXS or even thicker. The A709 Gr 50 carbon steel plate specification covers nominal wall and minimum wall chrome-molybdenum( also known as Cr-Mo, or Cr-Moly) alloy steel pipe intended for high-temperature application.
Common carbon killed steel plates are steel plates made by hot-rolling ordinary carbon structural steel killed billets. The advantage of A709 Gr 50 carbon steel plate, killed steel is that the chemical composition is uniform, so the mechanical properties of each part are also uniform, the welding performance and plasticity are good, and the corrosion resistance is strong. Common killed steel plates are mainly used to produce components that withstand impact at low temperatures, welded structures and other structural parts that require higher strength.
Fatigue wear often occurs on the rolling or rolling and sliding friction surface of the wear-resistant plate, A709 Gr 50 carbon steel plate. Under the action of alternating stress, the soft area of the surface will produce plastic deformation. When the stress exceeds the tensile strength of the material, cracks will appear in the weak places, and the cracks will continue to expand under the effect of stress. When the crack length reaches a certain value, it will cause fracture and cause the phenomenon of pitting and spalling.
SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. A709 Gr 50 carbon steel plate, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.
We have a professional production team and high-quality production equipment, and we also have a great A709 Gr 50 carbon steel plate advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the A709 Gr 50 carbon steel plate production of high-quality steel plates, steel pipes and other products that meet customer requirements.
The results of adopting two-level A709 Gr 50 carbon steel plate service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and A709 Gr 50 carbon steel plate after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
