Posted:2021-03-22 15:17:28

Q345A low alloy high strength steel: It can be used for building structural parts, shipbuilding, bridges, automobiles, locomotives, tractors, chemical containers, broadcasting tower high pressure containers, etc.

Q345B low alloy steel: Same as Q345A. Q345B steel is used for structural parts requiring normal temperature impact performance.

Q345C high strength steel: Same as Q345A. Q345C steel is used for structural parts requiring 0℃impact property.

Q345D low alloy high strength steel: Same as Q345A. Q345D steel is used for structural parts requiring low temperature - 20℃ impact performance, only for plate (strip) material.

Q345E high strength steel: Same as Q345A. Q345E steel is used for structural parts requiring low temperature -40℃ impact performance, only for plate (strip) material.

Q390A low alloy steel: Used for high and medium pressure vessels, shipbuilding, bridge vehicles, cranes, oil tanks, etc.

Q390B high strength steel: Same as Q390A. Q390B steel is required to be used as structural parts with normal temperature impact property.

Q390C low alloy steel: Same as Q390A. Q390C steel is used for structural parts requiring low temperature 0℃ impact performance.

Q390D low alloy high strength steel: Same as Q390A. Q390D steel is used for structural parts requiring low-temperature -20℃ impact performance, only for plate (strip) material.

Q390E high strength steel: Same as Q390A. Q390E steel is used for structural parts requiring low temperature - 40℃ impact performance, only for plate (strip) material.
