Carbon steel S550 steel shot used for bridge

API 5L X70 pipeline steel belongs to ultra-low carbon microalloyed steel. The production of API 5L X70 pipeline steel has almost applied all the new technological achievements in the field of metallurgy for more than 20 years. API 5L X70 pipeline steel is a product with high technology content and high added value. API 5L X70 hot rolled S550 steel shot high strength pipeline steel is one of the important products in pipeline steel, which requires high precision of hot rolling equipment and difficult process control.

Generally, the S550 steel shot, wear-resistant plates we use are made of a variety of alloys, and some metal elements are added. High-strength plates are heavier. We can reduce the quality of the wear-resistant plates through special treatment. So that the structure is lightened, the force of rain water on the wear-resistant plates will be weakened, and the damage to the wear-resistant steel plate will be reduced.

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 S550 steel shot 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.

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel S550 steel shot products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
