a242 type 1 steel mill A36 carbon steel plate

S235JR is a European standard non alloy structural steel, equivalent to the national standard Q235B, i.e. S235JR steel is carbon structural steel with low carbon content. S235JR steel is widely used in welding, bolt connection and riveting structures. S235JR steel is mainly used in railway, bridge, all kinds of construction engineering, manufacturing all kinds of metal components bearing static load and unimportant mechanical parts and a242 type 1 steel mill general weldments that do not need heat treatment.

What is the difference between Q345B steel and Q345A steel?
a242 type 1 steel mill, 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.
