In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product A709 Gr 50 high strength steel structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel A709 Gr 50 high strength steel supplier in the world.
BBNSteel served SA 516 GR 70 boiler quality plates to many industries like oil, gas, petrochemicals and because of having a high demand for sa516 Grade 70 boiler steel plates by our worldwide clients. We ensure that the A709 Gr 50 high strength steel material is always in stock and available to you from our warehouse. So we always make sure to provide all the ordered products on time with our big delivery network.
High wear resistance: fully automatic CNC stacking equipment, independent of manual A709 Gr 50 high strength steel welding technology, produces fully qualified high-quality products. Special automatic welding technology enables the chromium content of wear-resistant layer to be controlled at more than 28%, and the A709 Gr 50 high strength steel hardness is between 58-62, which fully ensures that our wear-resistant layer has continuous good and balanced wear resistance. The wear test in metallurgy, cement and other industries shows that the wear resistance of the wear-resistant layer of the surfacing composite A709 Gr 50 high strength steel wear-resistant steel plate is more than 30 times that of the 16Mn plate with the same thickness.
A709 Gr 50 high strength steel, Hardened wear-resistant plates are gradually annealed at a temperature higher than 250℃ to lose their hardness, which greatly reduces the wear resistance. The welding process will also reduce the hardness near the weld; the wear layer of the bimetal wear plate is of high alloy composition, and there is a secondary hardening effect at a certain temperature, and it can generally work below 650℃.
Chemical elements of 35CrMnSi steel: C: 0.32-0.39, Si: 1.10-1.40, Mn: 0.80-1.10, Cr: 1.10-1.40. The mechanical properties of 35CrMnSi steel: tensile strength 1620 MPa; yield strength 1280 MPa; elongation after fracture: 9%; reduction of area: 40; impact energy: 31J. A709 Gr 50 high strength steel, 35CrMnSi steel is used to manufacture medium speed, heavy load, high strength parts and high strength components, such as aircraft landing gear and high pressure blower blades. 35CrMnSi can partly replace the corresponding CrNi alloy steel in manufacturing small and medium section parts.
our company is leading supplier of API 5CT casing pipes in China. N80 oil casing pipes enjoy high size precision, good weld toughness, A709 Gr 50 high strength steel good extrusion resistance, easy quality control and low cost features.
