China S690QL1 EN 10025-6 high strength steel price

There are many types of S690QL1 EN 10025-6 high strength steel etc. alloy steel plates, which can be divided into different types according to different standards. If divided according to the element composition of the alloy, the alloy steel plates can be divided into four types. The first is chromium steel, in which chromium is an important part of alloying elements. The second type is chromium-nickel steel, the third is manganese steel, and the last type is silico-manganese steel. The types of these alloy steel plates are named according to the composition of the alloying elements contained in the steel, so you can roughly understand their composition based on their names.

In order to prevent the deformation of S690QL1 EN 10025-6 high strength steel, wear-resistant composite plate during preheating, the steel plate with good quality should be selected first. The steel plate with serious carbide segregation should be reasonably cast and heat treated by quenching and tempering. For the large and non cast wear-resistant composite plate, the solution double refining heat treatment can be carried out. At the same time, the heating temperature should be reasonably selected and the heating speed should be controlled.

Normalizing is a special case of annealing, the effect is similar to annealing, but the microstructure obtained by normalizing is finer. For low or medium carbon steel, normalizing can improve hardness and machinability. For S690QL1 EN 10025-6 high strength steel medium carbon steel and low alloy steel, normalizing can refine grain and uniform structure and reduce hardness. For high carbon steel and high alloy steel, normalizing can eliminate the network carbide produced by forging and improve the homogeneity of the preparation heat treatment structure.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
