Bearing steel is a kind of steel used to manufacture rolling bearings such as balls and rollers, and even sleeves. It can also be used to manufacture precision measuring tools and coupling parts. The physical properties of its bearing steels are very good. Generally speaking, they are made by heat If rolled annealing and cold drawing annealing are used for delivery, the delivery status should be specified in the contract.
We supply 5800 tons A53 Gr B ERW pipes to Qatar for Qatar Integrated Railway Project - Green Line. This is the first Metro Line in Qatar, and it is located in Doha. We got the order by tender, launched by the Qatar Railways Company for designing, construction and completion of Green Line Project. Before putting order, a delegation from the a242 weather resistant steel plate project side visited us and several other famous steel pipe mills in China for 15 days. Finally, we were chosen and finished the task exceeding their expectations.
The difference between a242 weather resistant steel plate, hot rolled sheet and cold rolled sheet: hot rolled sheet has low hardness, easy processing and good ductility. The cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The cold rolled sheet is mostly used in automobile manufacturing and electrical products. Therefore, the two have their own characteristics. According to these characteristics, it is more appropriate to choose the right rolled plate to maximize its effect and benefit.
The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, a242 weather resistant steel plate and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.
