Welcome to BBN High Strength Steels Factory
With the development of China's S690QL steel price market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of S690QL steel price products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.
SA516Gr60 meets the requirements of (ASME) ASTMA516/A516M standards, and meets the needs of oil gas with high content of sulfur and hydrogen, reducing sulfur and hydrogen corrosion, reducing equipment maintenance, and increasing equipment life. The steel S690QL steel price has the following characteristics: good impact resistance, low temperature deformation, good welding performance, good fatigue resistance, good anti-layer cracking performance, microalloying, high purity, low carbon equivalent, and strong resistance to sulfur and hydrogen.
S690QL steel price, Q345B low alloy steel has outstanding characteristics, such as: First, Q345B low alloy steel has good toughness. It is easy to bend and stretch, not easy to break, and can be used for multiple processing. Second, S690QL steel price, Q345B low alloy steel is easy to weld and can be used for assembly. Third, Q345B low alloy steel has good strength, good compression resistance and long service life. Fourth, the weather resistance of Q345B low alloy steel is good, and the use is not affected whether it is winter or summer.
The preparation of S690QL steel price galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for S690QL steel price centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
S355J2G3 is low alloy high strength structural steel, and it is roughly equivalent to GB Q345D.S355J2G3 is a European standard steel with composition of C ≤ 0.20, Si ≤ 0.55, Mn ≤ 1.60, P ≤ 0.035, S ≤ 0.035. The meaning of J2G3 indicates that the delivery state of S355J2G3 steel is normalized, the impact energy at - 20 ℃ is 27J. G3 and G4 indicate the deoxidization mode. S690QL steel price, S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.
