Q390A Q390D A390ND Metal H Beam
Q390A Q390D Q390ND Steel H Profile
Q390A is a kind of low alloy steel high-strength structural steel, and Q345 steel beam h than the strength level has been improved, with higher comprehensive mechanical properties, generally in the hot-rolled or normalized state. Suitable for the manufacture of medium and high pressure boiler ladle, high pressure petrochemical vessels, pipelines, bridges and other welded structural parts with high loads.
Q390D h type steel beam is not only high strength steel, it is also low carbon steel.Q390D h type beam has high yield strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming properties and welding performance; with good corrosion resistance and certain wear resistance.
Q390ND belongs to the low alloy high-strength structural steel plate, Q390ND h steel profile itself not only has high strength, but also carries high toughness, fatigue resistance, impact resistance, resistance to low temperatures, welding and easy processing performance.
