EN steel grade S690QL material Planing

After comprehensive and professional training such as customer service, the customer service team has more strict discipline in the management of customer service team to ensure that customer service personnel respond to customers with a professional attitude. A process supervision system has been set up to let each customer supervise the process of the system with us

EN steel grade S690QL material, Boiler steel plate is a kind of medium and heavy steel plate used to make important parts of boilers. From the material point of view, boiler steel plate can be divided into special carbon steel plate and low alloy heat resistant steel plate. According to the different working conditions, the boiler steel plate can be divided into two categories: manufacturing room temperature and medium temperature pressure bearing parts steel plate and manufacturing high temperature pressure bearing part steel plate. Boiler steel plate is widely used in petroleum, chemical industry, power station, boiler and other industries.

Titanium microalloying is an element of EN steel grade S690QL material 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 EN steel grade S690QL material 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.

A36 is American Standard ASTM material, SS400 is Japanese Standard JIS g3101 steel material for general structure, Q235 is Chinese standard GB700 material. The limitation of the content of the Mn element differs depending on the thickness of the A36 steel plate, and the A36 steel plate of 20 mm or less does not contain Mn. The EN steel grade S690QL material, Q235 steel plate has requirements for the contents of C, Si, Mn, S, P and other elements. But SS400 steel plate only requires S and P to be less than 0.050, and no other element requirements.

Our company doesn't need the cheapest quotation to choose international logistics company, but the price performance ratio will be high, the service will be good, and the transportation must be safe and punctual, which will not affect the time when the EN steel grade S690QL material goods arrive at the destination, and the logistics situation will be well communicated with customers in advance. Therefore, when we choose international logistics companies, we will have a look at their timeliness and service attitude in advance. It is only important to transport goods according to the requirements of customers for logistics.

It is a modern high-tech professional enterprise integrating scientific research, EN steel grade S690QL material production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as EN steel grade S690QL material process technology development, technology transfer and related technical consulting and technical services.
