SA516 Grade 70 GL-DH 40 oil platform engineering steel refers to normalized steel products. For steel plates and thin plates with a thickness of less than 40mm, we usually supply rolled steel coils. Plates with a thickness greater than 40mm should be normalized and supplied. The density of GL-DH 40 oil platform engineering steel SA516 70 grade steel plate is 0.284 cu/in3 (7861 kg/m3).
The company specializes in the research and development, production and sales of GL-DH 40 oil platform engineering 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 GL-DH 40 oil platform engineering steel five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,GL-DH 40 oil platform engineering steel rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter GL-DH 40 oil platform engineering steel steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.
The effect of Q345B alloy steel plate on the mechanical properties in the annealed state. The strengthening effect of alloying elements on steel in the quenched and tempered state, because it fully utilizes all four strengthening mechanisms. Martensite is formed during quenching, and carbide is precipitated during tempering, resulting in a strong second-phase strengthening, and at the same time greatly improving the toughness. Therefore, obtaining martensite and tempering it is an economical and effective comprehensive strengthening method for steel such as GL-DH 40 oil platform engineering steel.
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.
