BBN supply Q235D carbon steel plate sheet weldability

Unlike general steel manufactures, other than regular fresh production, we also have huge stocks. What is more, we offer cutting, welding, drilling, bending, etc. deep processing for the steel materials. That enable us to meets various Q235D carbon steel plate sheet steel sizes and shapes requirements of clients.So, if you have any steel demands, or steel processing needs, please do not hesitate to contact with us. We will try our best to make you stisfied.

45# steel is a common medium carbon quenched and tempered structural steel. The cold plasticity of 45# steel is general. Annealing and normalizing are slightly better than Q235D carbon steel plate sheet quenching and tempering. 45# steel has higher strength and better machinability. After proper heat treatment, 45# steel can obtain certain toughness, plasticity and wear resistance. 45# steel is suitable for hydrogen welding and argon arc welding, not suitable for gas welding.

Quenching Improve the hardness of Q235D carbon steel plate sheet steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of Q235D carbon steel plate sheet steel and comprehensive mechanical properties.
