The common uses of S500MC high strength low alloy steel, boiler and pressure vessel steel plate are as follows. First, make boilers and pressure vessels. Boiler and pressure vessel steel plate not only has a certain strength, but also has a certain ability to withstand impact. The boiler and pressure vessel steel plate should be resistant to abrasion and high temperature. Second, the boiler and pressure vessel steel plate is used to make spherical tank, oil gas tank, liquefied gas tank and other tanks. The boiler and pressure vessel steel plate should have the characteristics of corrosion resistance and pressure resistance.

The wear-resistant plate s500mc high strength low alloy steel shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and s500mc high strength low alloy steel hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.

Three advantages of semi-endless rolling technology: 1. The limit specification of Q345B steel is expanded from 1.5 mm × 1300 mm to 1.5 mm × 1600 mm. 2. the semi-endless rolling technology can effectively reduce the fluctuations in the temperature, size, and shape control accuracy of the strip head and tail. 3. The different parts of the strip steel s500mc high strength low alloy steel produced by semi-endless rolling have uniform structure and mechanical properties, the yield strength fluctuation is less than 40 MPa, and the tensile strength fluctuation is less than 20 MPa.

The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, s500mc high strength low alloy steel 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.

The results of adopting two-level s500mc high strength low alloy steel service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and s500mc high strength low alloy steel after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
