A medium tensile, low carbon manganese steel S355JR is readily weldable and possess good impact resistance. This material is commonly supplied in the untreated or normalized condition. Structural unalloyed steel ABS grade B hull structural steel coil has a wide range of applications in construction, metallurgy, heavy and transport engineering, machine tool, power engineering and bridge building industries. Various profiles and metal structures, parts and elements of ground and underground equipment are made from steel S355JR.
In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product ABS grade B hull structural steel coil structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel ABS grade B hull structural steel coil supplier in the world.
Last year, the technicians in the automation department of BBN STEEL closely combined the needs of the production line, based on the big data platform. It has successively developed more than 10 industrial software such as intelligent boiler combustion system, equipment full life cycle system, and integration of environmental protection management and control, which provide efficient and intelligent support for comprehensive support of high-end production line production and lays a solid foundation for high-quality development.
Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of ABS grade B hull structural steel coil etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in ABS grade B hull structural steel coil etc. steel is strictly controlled.
After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
