What is the scope of geometric dimension of a 573 gr 70 properties

The company specializes in the research and development, production and sales of a 573 gr 70 properties 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 a 573 gr 70 properties five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,a 573 gr 70 properties rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

GB711-2011 Chinese steel standard is used in the manufacture of steel plates with a a 573 gr 70 properties thickness of not more than 150mm for navigating ships, fishing boats and marine engineering structures in ocean, coastal and inland waterway areas. CCS/NV/GL550 steel is a structural steel for ships and marine engineering, divided into four quality grades A, D, E, F, namely AH550, DH550, EH550, FH550, H is high-strength building materials, and 550 is the lower yield strength.

The wear-resistant layer of a 573 gr 70 properties wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy a 573 gr 70 properties carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

The a 573 gr 70 properties, heavy steel marine steel plate has the characteristics of pure steel, stable performance and good surface quality, and can be delivered at full scale. The marine steel plates are widely used in the construction of the main structure and superstructure of 10,000-ton ocean-going ships, and can also be used to manufacture the hull structure of inland ships. With the improvement of equipment level and the continuous progress of technology, heavy steel marine plate has made great progress in the production of high-strength shipbuilding steel plates, and its products are extending to the high-end market.

The requirements for toughness impact energy of a 573 gr 70 properties, S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.

We are leading supplier of pipeline steel. The pipeline steel in usually in forms of pipeline steel coils, pipeline steel sheet, pipeline steel plate and pipeline steel pipes. And the most popular standard is API 5L. For questions about a 573 gr 70 properties pipeline steel, such as X70 steel properties, API 5L X42 steel properties, difference between API 5L PSL1 and API 5L PSL2, API 5L grade B steel price, please feel free to communicate with us.

We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
