The controlled cooling process of EN 10025-6 S550QL high strength steel

In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like EN 10025-6 S550QL high strength steel, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.

The main characteristics of EN 10025-6 S550QL high strength steel, 12Cr1MoV alloy steel plate are as follows:Compared with 12CrMoV steel, 12Cr1MoV alloy steel plate has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is close to the stress rupture strength, and it has high plasticity under the condition of long-term tension. The process and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress relief treatment is required after welding.

As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another EN 10025-6 S550QL high strength steel magnificent projects.

Strengthen system construction. The system itself has a certain binding force, which specifies the rights and obligations of employees. It is a passive management means for employees. Its purpose is to promote each employee to develop good professional habits, form good behavior norms, and promote the improvement of enterprise management level.
