Welding technology of S690QL mechanical properties

Common grades of carbon structural steel plates: A36, A283Grade C, A572Grade 60, A573Grade 70, Q235B, Q235C, S235JR, S275J0, SS400, St37-2, S690QL mechanical properties, St52-3. Our company can provide carbon structural steel plate thickness ranging from 6 to 300mm. These plates are widely used in various types of engineering structures such as steel structure buildings, construction machinery, heavy vehicles, bridges, pressure vessels. Besides, we can provide Q235B carbon steel plate with Z direction test.

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel S690QL mechanical properties products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the S690QL mechanical properties market and has strong competitiveness.

Cold rolled S690QL mechanical properties steel sheet can be produced by two high mill, four high reversing mill, multi high reversing mill and tandem cold mill. Although there are still only two work rolls in four high and multi high rolling mills, each work roll is supported by one or more large diameter backup rolls, which can prevent deflection of work roll. As a result, wide and thinner S690QL mechanical properties steel plates can be produced. For example, 20 high mill can produce as thin as 0. 001 mm sheet, but the two high mill can only produce as thin as 0. 35mm sheet

Boiler steel is different from S690QL mechanical properties. Boiler steel is used to make boilers. Boiler steel can be divided into steel for boiler steel pipe, boiler steel plate and boiler steel fasteners. Boiler steel is smelted by open hearth furnace, converter, electric furnace, and some also use the refining process outside the furnace. Boiler steel for steel pipes refers to the steel used for the manufacture of superheaters, reheaters and headers. Their working temperature is higher than other parts, and the environment is also harsher.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
