We are a popular factory, supplier and wholesaler of mild steel plates and alloy steel plates in all over the globe. We follow all standards and specifications of A709 Gr HPS100W bridge steel plate boiler steel plate, structural steel plate, shipbuilding steel plates and corten steel in different types. We manufacture and supply steel plates, steel section and steel structures according to customer’s demand. The company also focus on providing customers with A709 Gr HPS100W bridge steel plate high-end steels and competitive price.
If A 515 grade 70 pressure vessel plates thick in 50mm or under this thickness, A709 Gr HPS100W bridge steel plate, A515 Grade 70 plates are supplied in the as-rolled condition. Normalizing treatment can be ordered, but those greater than 2 inch (50 mm) in thickness must be delivered in normalizing state. A515 Gr 70plate and sheet are widely used in petroleum, chemical industry, power station, boiler and other industries. It is used to make reactor, heat exchanger, separator, spherical tank, paint tank, liquefied gas tank, nuclear reactor pressure shell, boiler drum.
Shipbuilding steel plates are used to manufacture marine and inland ship hulls, which require high strength, plasticity, toughness, cold bending performance, welding performance, and corrosion resistance. BBN steel company produces various grades steel plates for shipbuilding like AH32, AH36, AH40, DH32, DH36, EH32, EH36, A709 Gr HPS100W bridge steel plate and can produce marine steel plates and sheets with different certificates according to client needs.
Processing performance of quenched and tempered steel: A709 Gr HPS100W bridge steel plate plate can be used for cold working, bending and cutting. When the gas is cut off, cracks will not occur even without preheating. When preheating processing, quenched and tempered steel needs to be processed below the tempering temperature. Superb wear and corrosion resistance: Because it contains alloy elements such as copper and chromium, it has good corrosion resistance, higher hardness, and good wear resistance compared with ordinary steel.
20# seamless steel pipe chemical composition: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25. 20# seamless steel pipe mechanical properties: recommended heat treatment temperature: 910℃, tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%, impact energy is not required. 20# seamless steel pipe hardness is higher than 10# seamless steel pipe. A709 Gr HPS100W bridge steel plate, 20# seamless steel pipe has good weldability, no temper brittleness, and its machinability can be improved by water quenching. 20# seamless steel pipe can be used to make welded components, as well as parts with small load after forging, hot stamping and cutting.
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.
