Q high yield Strength Quenched and tempered alloy steel plate suitable for the rack of construction machinery and jack up offshore drilling platform. Available steel plate specifications range: thickness 8-650mm, width 1500-4020mm, length 4000mm-17000mm. Our company can supply alloy steel plates every month 500tons.The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy NM450 steel grade products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of NM450 steel grade stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This NM450 steel grade rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.The NM450 steel grade, heavy steel marine steel plate has the characteristics of pure steel, stable performance and good surface quality, and can be delivered at full scale. The marine steel plates are widely used in the construction of the main structure and superstructure of 10,000-ton ocean-going ships, and can also be used to manufacture the hull structure of inland ships. With the improvement of equipment level and the continuous progress of technology, heavy steel marine plate has made great progress in the production of high-strength shipbuilding steel plates, and its products are extending to the high-end market.Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, NM450 steel grade sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
