Q235A and Q235B, the main difference lies in the carbon content, carbon content of Q235A in 0.14-0.22, Q235B carbon content in 0.12-0.20
Relatively speaking Q235B mechanical performance is far superior to Q235A steel. Which Q235B do stamping experiment, Q235A do stamping experiment.
Q235A good toughness, has a certain degree of elongation, good welding and processing of. Q235A general in the hot state, the rolled steel, steel, steel plate, steel tube can be used for manufacturing various welding structures, bridges and generally not significant parts of the machine, such as bolts, rivets, pull rod, ring and the connecting rod.
Q235B has a certain degree of elongation, strength, good toughness and casting of. Ease of stamping and welding, widely used in general machinery parts manufacturing. Mainly used for construction, bridge engineering quality requirements of high structure.

Is steel plate Q345B property equivalent to A572 50?
q345b is equivalent to grade 50
What are the specifications of Q345B steel?
Q345B is black carbon steel. The specification of a Q345B steel sheet depends on what you want and ranges from 6 to 120mm thick, 1600 to 3200mm wide and 6000 to 12000mm long.
What is difference between between Q345 and S355 steel?
S355 is slightly stronger than Q345B, and the welding is exactly the same. S355NL grade is a normalized steel (fine-grained steel) in the EN10025-3:2004 standard. EN 10025-2 S355JR material is a low-alloy high-strength structural steel that meets the European standard EN10025. ensteelstandardcom/FAQ/what-is-the-difference-between-s355-and-q345b-steel.html
