What is the BBNSteel company JIS SM490YB plates main products

With the development of China's JIS SM490YB plates 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 JIS SM490YB plates products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.

Q370qC, Q370qD, JIS SM490YB plates and Q370qE are structural steel plates for bridges. It is required to have high strength, toughness and to withstand the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The steel for tie-welding bridges should also have good welding performance and low notch sensitivity. Used for the production of riveted and bolt-welded road bridges and railway bridges (including cross-sea bridges).

The wear-resistant layer of JIS SM490YB plates wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy JIS SM490YB plates carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

The mechanical properties of JIS SM490YB plates, boiler pressure components steel include strength, plasticity, toughness and fatigue properties. Temperature has a great influence on the mechanical properties of steel. With the increase of temperature, the yield limit of all kinds of steel will monotonically decrease, but the tensile strength will rise to a high peak at a certain temperature, and then decrease.

2020 October JIS SM490YB plates specification: 8*2200*10000, 16*2150*10400, 30*2500*6200, 31.2*2950*9380, 7*2200*8000, 30*2200*10000, 14*2400*9900, 18.5*2700*9570, 21*2100*8810, 14*2070*9060, 12*2200*10000, 14*1950*8000, 36*2200*7700, 7*2200*8000, 14*2070*9060, 10*2200*8000, 20*2500*10000, 14*2400*10000, 30*2000*7400, 6*2800*12000, 21*2100*8810, 32*2200*10000, 16*2150*10250, 27*2500*9000, 20*2100*7000, 21*2100*9100.

The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, JIS SM490YB plates 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.
