At the same time, the company operates a variety of products of related iron and A709 grade 50 carbon steel plate steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained A709 grade 50 carbon steel plate ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.
EN10025-3 S460NL material is a hot rolled low carbon manganese steel. It has min. 460Mpa yield strength and low temperature impacting at -50℃ with minimum energy 27 J. A709 grade 50 carbon steel plate, S460NL also has good weldable property and possess good impact resistance (also in sub-zero temperatures). We supply S460NL steel plate for deep oceans, bulit the tanks or structural parts of nuclear submarine all over the world. Large stock of S460NL hot rolled plate available in India, Bangladesh, Malaysia, Nigeria, South Africa & UAE.
The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with A709 grade 50 carbon steel plate, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.
Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while A709 grade 50 carbon steel plate steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of A709 grade 50 carbon steel plate steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
