ASTM A36 Q235 Q345 Ss400 Mild Ship Building Hot Rolled Carbon Steel Plate

Q: Is Q235 plate easy to weld?
A: Yes. Q235 plate has excellent weldability. It can be welded by various welding methods such as arc welding, gas welding, resistance welding, etc., without preheating or post-heating under normal circumstances.
Q: Can Q235 plate be bent? What is its minimum bending radius?
A: Yes. Q235 plate has good bending performance. The minimum bending radius is generally 1~2 times the plate thickness (depending on the bending angle and plate thickness).
Q: Can Q235 plate be punched and sheared?
A: Yes. Q235 plate has good cold working performance and can be processed by punching, shearing, blanking and other cold working methods.
Q: Can Q235 plate be heat treated to improve its strength?
A: Q235 plate is a low-carbon steel, and its hardenability is poor. Heat treatment (such as quenching and tempering) can not significantly improve its strength. If higher strength is required, it is recommended to choose high-strength steel plates.
Q: What is the machinability of Q235 plate?
A: Q235 plate has good machinability. It can be processed by turning, milling, drilling, planing and other methods, and the processing tool wear is small.
