How to visually distinguish whether it is hot rolled or cold rolled 51crv4 spring steel for turbine rotor
The company is a large 51crv4 spring steel for turbine rotor steel supplier and exporter specializing in steel coil, steel plate, steel tube and section steel. The company has always put service and quality first, offered reasonable price, taken small profits and quick turnover as the principle, honest and trustworthy as the purpose. The success of the company is not only the hard work and wisdom of all the employees of the company, but also the deep love of our customers. We will continue to achieve new leaps and create greater brilliance of the 51crv4 spring steel for turbine rotor enterprise, and make our own contribution to the development of the world economy.
Marine steel is widely used in all kinds of ships and offshore platforms, but it also puts forward higher and higher requirements for marine steel. In general, the demand share of 51crv4 spring steel for turbine rotor high-strength marine steel continues to increase. In terms of strength requirements, with the change of ship's large-scale, safety and coating specifications, the general trend is that the consumption of ordinary strength grade A marine steel plate is gradually reduced, and the consumption of high-strength marine steel plates is increased.
The difference between 51crv4 spring steel for turbine rotor, 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.
Experiments have proved that the outstanding feature of the precipitation-strengthened 51crv4 spring steel for turbine rotor, wear-resistant plate in terms of mechanical properties is that the yield strength is greatly improved. For example, the yield strength of the wear-resistant plate after precipitation strengthening treatment reaches 480-8l0MPa, and the yield strength ratio is 0.55-0.56; the wear-resistant plate that uses molybdenum, vanadium, and iron composite alloying, the yield ratio after dispersion strengthening is 0.60- 0.65.
