The company specializes in the research and development, production and sales of Q355GNH cold rolled weathering steel angles seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has Q355GNH cold rolled weathering steel angles five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,Q355GNH cold rolled weathering steel angles rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
40CrNiMoA alloy steel materialGrade 40CrNiMoA Standard: GB/T 3077-2015Advantages: hardenability and stability against overheatingApplication: shafts, gears, fasteners, etc.Raw materials: carbon, silicon, manganese, etc.
We exported 2150 Tons SG295 steel coils to Sudan. The Sudan customer is LPG cylinder manufacturer. Before our cooperation, he usually purchased SG295 steel coils from UAE and Turkey. And he got to know our company through our regular customers in Uganda, UAE, and his friends in China. Then he gave us the order. We invited the customer to visit us before contract, but he insisted to visit us when the Q355GNH cold rolled weathering steel angles goods are finished production. After inspecting the size, package in workshop and witness the lab test for the SG295 steel coils, the customer was very satisfied to our quality control and professional arrangement.
Heat treatment advantages of Q355GNH cold rolled weathering steel angles, SA516 Gr 70 pressure vessel steel: 1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased. 2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness. 3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition. 4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.
The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate Q355GNH cold rolled weathering steel angles EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
