GB/T1591 Q345A I beam /angle/ channel steel
decreases the yield value as the thickness of the material increases. And may be less than 345, so when the mechanical design strength must be less than the value of 345, otherwise there will be problems. For the detection of GB/T1591 Q345A I beam /angle/ channel steel, on the one hand whether the element content of steel reaches the national standard requirements, the most important one is through The professional body tests whether the mechanical properties of the steel (yield strength, tensile test) meet the standards.

The application of GB/T1591 Q345A I beam /angle/ channel steel :
GB/T1591 Q345A I beam /angle/ channel steel market price is lower than GB/T1591 Q345B, C, D, E, GB/T1591 Q345A I beam /angle/ channel steel is a low alloy steel, widely used in bridges, vehicles, ships, construction, pressure vessels and so on. Q represents the yield of this material, and the 345 behind it refers to the yield value of this material, which is around 345 MPa. And as the thickness of the material increases its yield value decreases.

The bellow is the channel specification of GB/T1591 Q345A I beam /angle/ channel steel:
