Export great S690QL equivalent ASTM to Canada

Grade DH36 ship steel plate is a high-strength ship plate. Shipbuilding steel generally refers to the steel used for hull structure. It refers to the steel used for manufacturing the hull structure produced in accordance with the requirements of the classification society construction codes. S690QL equivalent ASTM, DH36 ship steel plate is often ordered, scheduled, and sold as special steel. We can supply various sizes and shapes of ship steel like plates , steel angles, bulb flat, steel channel and section steel.

The company attaches great importance to systematic management, and has passed the S690QL equivalent ASTM ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on S690QL equivalent ASTM quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This S690QL equivalent ASTM production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate S690QL equivalent ASTM size.

After extrusion, the S690QL equivalent ASTM tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.
