Hot Rolled S690QL quenched and tempered material Mild Carbon Steel Plate

The quality of S690QL quenched and tempered material shall not only meet the requirements of the standard, but also be higher or stricter than the product characteristics specified in the standard, including chemical composition, structure, physical properties, chemical properties and other requirements of S690QL quenched and tempered material buyer, such as packaging, delivery time, etc.. On the basis of the quality of S690QL quenched and tempered material in line with the corresponding standards, some buyers will put forward specific requirements according to their own use requirements, which is called technical agreement. That is, some specific factors should be met according to the buyer's requirements. These requirements may be the control of chemical element content of S690QL quenched and tempered material and certain performance limit of S690QL quenched and tempered material, etc.

The company's operation is based on the principle of "quality for survival, reputation for development". In terms of management, we adhere to the principle of people-oriented, service-oriented and customer-oriented. All staff of the company have the courage to open up, unite and forge ahead, and work hard to grasp the good situation of global economic development, actively strengthen communication with outstanding enterprises in the S690QL quenched and tempered material industry, keep pace with the times, and move towards a new course!

Three advantages of semi-endless rolling technology: 1. The limit specification of Q345B steel is expanded from 1.5 mm × 1300 mm to 1.5 mm × 1600 mm. 2. the semi-endless rolling technology can effectively reduce the fluctuations in the temperature, size, and shape control accuracy of the strip head and tail. 3. The different parts of the strip steel S690QL quenched and tempered material produced by semi-endless rolling have uniform structure and mechanical properties, the yield strength fluctuation is less than 40 MPa, and the tensile strength fluctuation is less than 20 MPa.

API 5L X65 steel plate/pipes, under API 5L standard, we can regard X65 steel plate/pipes as large diameter pipes. S690QL quenched and tempered material, X65 steel plate/pipes is one mainly of Steel for large diameter pipes,API-X65 steel pipes/plate is a higher strength, tough, weldable steel for applications in the oil and gas industry.X65 Flange Steel meets fully the mechanical property requirements of the API 5LX X65 line pipe specifications whilst maintaining a high degree of toughness and weldability.

Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world. We regularly conduct quality tracking and return visits by phone and email, listen to customers' opinions, and continuously improve service quality.
