What is the difference between Q345B steel and Q345A steel? NM500 steel properties, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 020, Mn ≤ 17, Si ≤ 055, P ≤ 0045, S ≤ 0045, V 002 ~ 015; Q345B steel: C ≤ 020, Mn ≤ 17, Si ≤ 055, P ≤ 0040, S ≤ 0040, V 002 ~ 015 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,NM500 steel properties.

The cold working performance of and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of and so on steel structure engineering steel is good Durability refers to the service life of steel structure The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load,NM500 steel properties.
