Hot rolled S690QL material specification

Titanium microalloying is an element of S690QL material specification strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in S690QL material specification tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.

The S690QL material specification atmospheric corrosion resistance of high weather resistant structural steel is better than that of welding structural weathering steel, and is mainly used for bolt connection, riveting and welding structural parts for vehicles, containers, buildings, towers and other structures. But the welding performance of welding structural weathering steel is better than that of high weather resistant structural steel, and the welding structural weathering steel is mainly used for welding structural parts for bridges, buildings and other structures.

In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
