nm450 steel density Specification
With the development of China's NM450 steel density market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of NM450 steel density products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.
The advantages of NM450 steel density, steel plate produced from coil: price is cheap and length can be freely determined; transportation is convenient, no need to consider according to the size of steel plate; cutting is convenient, according to the actual needs of steel plate size cutting, and finally can effectively save materials. The disadvantage of steel plate produced from coil: there will be great welding deformation during welding, which is difficult to adjust. Therefore, the steel plate produced from coil can not be used for parts with high requirements on appearance quality.
Boiler steel plates for room temperature and medium temperature (below creep temperature) are mostly carbon steel, including carbon steel, carbon manganese steel, carbon manganese silicon steel, NM450 steel density, etc. They are mainly used in the manufacture of pressure-bearing parts such as boiler drums and header end covers below medium temperature. High temperature (above creep temperature) boiler steel plates are mainly used to manufacture high-temperature pressure-bearing parts such as high-temperature header end caps and steam pipe blocking plates.
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 NM450 steel density 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 NM450 steel density steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
In steel standard JIS G3106, SM570 steel owned the highest yield strength above 460 Mpa, and the tensile strength within 570-720 Mpa. For SM570 steel, the C element content is 0.18%, the Si element content is 0.55% max, the Mn element content is 1.60% max, the P element content is 0.035% max, the S element content is 0.035% max. NM450 steel density, SM570 steel with thickness from 6mm-300mm,width from 1500mm-4000mm,length from 5000-16000mm.
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.
