ASTM A36 h beam is a common wide flange beam used in construction and machinery for its medium strength. Low carbon content makes it easy to be welded, machined as well as formed. Therefore, it is often employed by light applications where strength need

ASTM A36 h beam is a common wide flange beam used in construction and machinery for its medium strength. Low carbon content makes it easy to be welded, machined as well as formed. Therefore, it is often employed by light applications where strength need is not so important.

What is the difference between Q345B steel and Q345A steel?
, Q345B steel and Q345A steel have slight difference in chemical composition:
Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15;
Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15.
The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.
