Technical Parameters

Q420 Q460 H Profile Steel

Q420, is a kind of low alloy high strength structural steel.Q420 H beam metal has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming properties and welding properties; good corrosion resistance and certain wear resistance. High strength, especially in the normalised or normalised plus tempered state has high comprehensive mechanical properties.

Q460 H beam structure is a kind of high-strength low alloy steel.Q460 grade expression: its steel number is crowned with "Q", which represents the yield point of steel, that is, yield strength. The latter number represents the yield point value of 460 represents 460 MPa, megapascal is 10 to the sixth power, pascal is the pressure unit pascal. Q460 is the steel strength to reach 460 MPa plastic deformation will occur, that is, when the external force is drained off, the steel can only maintain the shape of the force can not be restored to its original shape, the strength is greater than the general steel.
