What is the price of ASTM A709 structural steel sheet, low alloy steel plate? The low alloy steel plate quality of different manufacturers is different. Generally speaking, the quality of ASTM A709 structural steel sheet, low alloy steel plate produced by famous manufacturers will be better guaranteed, and the price is also relatively expensive. Besides, it is related to the grade of low alloy steel plate. The better the performance, the higher the price. In addition, it is related to the specification of ASTM A709 structural steel sheet, low alloy steel plate. And the price of different size and thickness plate is different. Finally, we can learn more information about ASTM A709 structural steel sheet, low alloy steel plate price through the comparison of multiple manufacturers or through the Internet.
Wear resistant steel is very wear-resistant: for example, excavator bucket, long-term excavation requires good wear resistance. Wear resistant steel has a very high hardness: for example, scraper conveyor, if the hardness is not up to standard, it is extremely easy to fracture, resulting in very serious consequences. Wear resistant steel has good corrosion resistance: many equipment need to transport chemical corrosion products, so corrosion-resistant mechanical equipment is needed. ASTM A709 structural steel sheet, Wear resistant steel has good fatigue resistance: such as bearing steel ball, which can do fast and repeated movement, and need to guarantee performance.
The chemical composition of 20CrMo steel pipe is 0.17-0.24, Si: 0.17-0.37, Mn: 0.40-0.70, Cr: 0.80-1.10, Mo: 0.15-0.25. Mechanical properties of 20CrMo steel pipe: tensile strength 410 Mpa; yield strength: 265mpa; elongation after fracture: 24; reduction of area: 60; impact absorption energy: 110J. 20CrMo steel pipe belongs to alloy structure steel pipe, which has high thermal strength, good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance at 500-520℃. ASTM A709 structural steel sheet, 20CrMo steel pipe is generally used in quenching and tempering state.
