Q690E material has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance. In addition, P235GH equivalent material, Q690 high strength steel plate and sheet has good corrosion resistance and certain wear resistance. High strength, especially in the normalizing or normalizing plus tempering state has a higher comprehensive mechanical properties.

The company specializes in the research and development, production and sales of p235gh equivalent material seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has p235gh equivalent material five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,p235gh equivalent material rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

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 p235gh equivalent 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.

The purpose of alloying Q345B steel is to use the interaction of alloy elements with iron and carbon and the effect on iron-carbon phase diagram and the heat treatment of steel to improve the structure and properties of steel. Interaction of alloying elements with iron and carbon: After alloying elements are added to steel, they mainly exist in steel in three forms. That is: forming a solid solution with iron; forming carbides with carbon; and possibly forming intermetallic compounds in high alloy steels, p235gh equivalent material.

Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our p235gh equivalent material service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's p235gh equivalent material customer service to establish a good, comprehensive, full service system.
