EN10025-6 S690 steel is a quenched and tempered high-strength non-alloy steel plate. The series of grades are S690Q, S690QL, and S690QL1. They are in accordance with the European standard EN10025-6. The steel specified in this standard can be used for the production of hot-rolled plates with steel grades P295GH steel for boiler, S460, S500, S550, S620, S690, S890, S960 series steel plates with a minimum nominal thickness of 3mm and a maximum nominal thickness of ≤150mm.

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, p295gh steel for boiler based on a high starting point and high technology, the company has vigorously developed various steel products p295gh steel for boiler and deep-processed parts, steel structures, precision castings, seamless pipes.

Titanium microalloying is an element of p295gh steel for boiler 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 p295gh steel for boiler 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 allowable temperature of p295gh steel for boiler, boiler steel is mainly determined by strength condition. Different steels have different mechanical properties and high temperature properties. Even for the same kind of steel, the tensile strength, yield strength and rupture strength vary greatly with the working temperature, and decrease with the increase of working temperature. In order to ensure the safety of p295gh steel for boiler work, the actual stress of p295gh steel for boiler under the working temperature should be less than the allowable stress determined by the tensile strength, yield limit and permanent strength of p295gh steel for boiler under the temperature.

The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
