Pipeline steel A131 grade D ship repairing steel refers to the hot rolled coil plate or wide thick plate used to transport oil, natural gas and other large-diameter welded steel pipes. In the process of using pipeline steel, it is required not only to have high compressive strength, but also to have high low temperature toughness and excellent welding performance. Pipeline steel plates are used to make oil and gas pipelines. The main A131 grade D ship repairing steel pipeline steel grades are API 5L grade B, API 5L X42, API 5L X60, API 5L X65 and so on.
The company specializes in the research and development, production and sales of A131 grade D ship repairing steel 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 A131 grade D ship repairing steel five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,A131 grade D ship repairing steel rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
Punchability refers to the performance of metal without cracks and other defects after stamping deformation. Many steel products are manufactured through a stamping process. In order to ensure the quality of the products and the smooth progress of the process, the A131 grade D ship repairing steel, steel plates and strips used for stamping must have qualified stamping performance.
Alloy steel plate: The primary purpose of adding alloy elements to steel is to improve the hardenability of the steel, and it is easy to obtain martensite during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are smaller, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, A131 grade D ship repairing steel.
