What is the laser cutting tolerance for quality 09CuPCrNi-B steel

The main challenges facing the current low-carbon development of the steel industry are as follows: First, insufficient energy resource endowments, coal and coke account for nearly 90% of energy input. Second, the crude steel output is relatively large, accounting for more than half of the global output. Third, there are a large number of enterprises, with more than 500 enterprises with smelting capabilities, and their structure and level are quite different. Fourth, the carbon emission mechanism is complex, involving multiple carbon emission mechanisms such as energy combustion emissions, indirect emissions corresponding to electricity and heat consumption.Corrosion resistant steel plate, as a new generation of advanced steel material, has 2-5 times of atmospheric corrosion resistance as ordinary carbon steel such as quality 09CUPCRNI-B steel, and the longer the service time, the more prominent the corrosion resistance. Due to its characteristics of rust resistance, coating free, thinning and consumption reduction, labor saving and energy saving, corrosion resistant steel plate can be applied to steel structures exposed to the atmosphere for a long time, such as buildings, vehicles, bridges, towers, etc., and can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, etc.Asme sa514gr.A high strength steel coil element composition%C: 0.15-0.21, Si: 0.40-0.80, Mn: 0.80-1.10, P max.: 0.035, S max.: 0.035, B max.: 0.0025, Cr: 0.50-0.80, Mo: 0.18-0.28, Zr: 0.05-0.15The mechanical properties in thickness (mm)T≤65Yield strength (≥Mpa): 690Tensile strength (Mpa):760-895Elongation in ≥,%: 18Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, quality 09CUPCRNI-B steel sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding.
