ASTM A387 Grade 5 and ASTM A387 Grade 9 Steel plates normal strength hull structural steel GL-B have good corrosion and heat resistance for alloy element chromium and molybdenum, which is needed in sour oil gas industry.
The company is a leading steel production and exporting group in steel materials with advanced production technology, metal-cutting skill, and steel structures engineering projects. We can supply carbon steel plate and sheet, alloy steel plates and structural normal strength hull structural steel GL-B steel plates. These hot rolled steel plates are sturdy plates having high quality. Their imperviousness to effect and scrapped area, weld capacity, and workability make them a worthy product in a variety of industries.
As the thickness and hardness of normal strength hull structural steel GL-B increase, the tendency to crack at the cutting edge increases. In order to prevent the normal strength hull structural steel GL-B from cutting cracks, preheating should be carried out before normal strength hull structural steel GL-B cutting. Special attention should be paid to preheating to make the entire normal strength hull structural steel GL-B interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole normal strength hull structural steel GL-B cannot be preheated, the partial preheating method can be used instead.
Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of normal strength hull structural steel GL-B, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.
Our quality and service commitment: normal strength hull structural steel GL-B product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.
