The company adheres to the A709 Gr 100 bridge steel plate external market, internal management, quality and efficiency oriented development path, and has achieved good economic and social benefits. With strong financial strength, advanced management experience, excellent sales service, strict quality management system and scientific overall marketing means, we will work hand in hand with you for common development. We are making all efforts working on the optimization of A709 Gr 100 bridge steel plate quality and price and best service for all our customers.
ASTM A387 Grade 5 and ASTM A387 Grade 9 Steel plates A709 Gr 100 bridge steel plate have good corrosion and heat resistance for alloy element chromium and molybdenum, which is needed in sour oil gas industry.
Low-alloy high-strength steel grades are designed to have quite good notch toughness for their intended structural use. The applicability of the notch toughness of specific grades of low-alloy high-strength steel is either based on existing use experience or combined with the results of the impact test of notched specimens. In order to meet the very strict requirements of certain applications, some A709 Gr 100 bridge steel plate, low-alloy high-strength steels produced have excellent notch toughness. For example, controlled hot rolling technology is usually used to produce low-alloy high-strength steel plates for the manufacture of welded line pipes. Such steel pipes need to meet the requirements of relevant standards for notch toughness.
Due to the existence of this dense oxide film, the infiltration of oxygen and water into the steel matrix in the atmosphere is prevented, the development of corrosion into steel material is slowed down, and the atmospheric corrosion resistance of steel material is greatly improved. A709 Gr 100 bridge steel plate, Weathering steel is a kind of steel system which can be used thinly, exposed or simply painted, and make products resistant to corrosion, prolong life, save labor and reduce consumption, upgrade and replace.
20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, A709 Gr 100 bridge steel plate. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.
It is a modern high-tech professional enterprise integrating scientific research, A709 Gr 100 bridge steel plate production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as A709 Gr 100 bridge steel plate process technology development, technology transfer and related technical consulting and technical services.
The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
