Heat treatment of a516 grade 70 density

For the team, cooperation is the core idea of daily work, and the core of common cooperation is resource sharing. With a perfect resource sharing mechanism, the whole team can be called a unity spirit.A good team lies in the ability to transfer resources, knowledge and information in time among team members in order to achieve the common goals of the team. So that we can share experiences and lessons."

High toughness and low brittleness transition temperature: with the increase of the working pressure of the a516 grade 70 density gas pipeline, the pipe diameter becomes larger, and the pipeline fracture accidents often occur. Toughness is the key factor affecting pipeline fracture. In order to ensure a516 grade 70 density pipeline safety, toughness and strength must be improved at the same time.

Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and a516 grade 70 density steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and a516 grade 70 density medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.
