With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of Q235NH weathering bridge steel coil leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.
On the morning of October 13, 2019 Zhengzhou International Marathon gave opening shoots in the Ruyi Lake, CBD, Zhengdong New District. This event was the “Running China” series of activities for the 70th anniversary of the Fouding of the People's Republic of China. There were 26000 participants Q235NH weathering bridge steel coil from 32 countries and regions including China, the United States, Italy, Russia, Spain, Ethiopia, and Kenya to witness the vicissitudes of "International Zhegnzhou". In the fierce competition, the Africa players once again showed their super strength and won the men’s and women’s full marathon championships.
SA36 carbon structural steel is a material belonging to the ASME boiler and pressure vessels. The products are produced in steel plates, steel sheets, steel bars, and section steels. The tensile strength is 400-550MPa; the yield point is greater than or equal to 250MPa. SA-36 steel production process: the steel is killed steel. Detailed specifications: Q235NH weathering bridge steel coil thickness: 8-100mm, width: 1600-4020mm, length: 6000-17500mm. It is commonly used in the construction of bridges and buildings.
Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This Q235NH weathering bridge steel coil alloy steel Q235NH weathering bridge steel coil still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.
