BBN steel keeps sa573 grade 70 structural quality carbon steel plate in stock

sa573 grade 70 structural quality carbon steel plate, A588GrB material is a high-strength low-alloy structural steel in shapes of profiles, plates and bars. Through the alloying of Cu, P, Cr, Ni, a protective layer is formed on the surface of the metal substrate, so that A588GrB steel has a high resistance to atmospheric corrosion. A588GrB high-strength low-alloy steel is widely used in various weather-resistant building structural parts (especially for industrial atmospheric environments), bridge auxiliary structural parts.

API 5L X65 steel plate/pipes, under API 5L standard, we can regard X65 steel plate/pipes as large diameter pipes. sa573 grade 70 structural quality carbon steel plate, 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.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the sa573 grade 70 structural quality carbon steel plate steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

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.
