The loose coil annealed s355j2 n steel steel sheet (O.C.A) developed by the United States is a special annealing of the boiling steel sheet in an atmosphere containing water vapor and hydrogen, because annealing in this atmosphere can remove the solid solution and carbides in the steel The compound carbon in the medium suppresses the aging sensitivity and further softens the s355j2 n steel steel plate.
Q345D seamless pipe has good comprehensive mechanical properties, low temperature impact toughness, cold stamping and cutting processability, weldability. In Q345D seamless pipe, Q is the abbreviation of yield strength, 345 is the yield strength value, that is, the yield strength of Q345D seamless pipe is 345 MPa, and D is the impact temperature, which is minus 20℃. s355j2 n steel, Q345D seamless pipe is widely used in various welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, storage tanks, heavy machinery and equipment, mining machinery, power stations, plant structures, low-temperature pressure vessels, textile machinery parts, etc.
