Half, 12Cr1MoVG alloy steel pipe in the field using 12cr1movG present, China's total consumption accounts 12Cr1MoVG alloy pipe steel in developed countries accounts for only expanded to provide a broader space for development of the industry. Based on the Chinese Special Steel Association 12Cr1MoVG alloy pipe branch, the future growth of China's annual demand for high-pressure alloy pipe 12Cr1MoVG longs up to 10-12%. 45 # 45 # steel seamless steel pipe generally applicable to the material, divided into seamless steel pipe GB8162, GB8163 two commonly used, but only GB8162 only 45 # steel, 45 # is a commonly used material abrasion machining Elbow, A3 I'm not clear estimate duct fluid pipe belongs to a bi-metallic composite wear elbow, is likely to do the testing. First, it is 20 # and 45 # steel c, Si, Mn, P, S content is different than 45 20 # steel bimetal composite wear elbow, you can just buy the steel manual look. 20 # steel hardenability, low hardenability, ductility, toughness, good weldability, toughness and better hot-rolled or normalized, can be made less important, the small carburizing, carbonitriding parts, forging parts, If the lever shaft, gearbox shift forks, double metal composite wear elbow gear, heavy machinery rod, hook ring. 45 # carbon steel is commonly used in quenched and tempered steel, good mechanical properties, low hardenability, prone to cracking during water quenching. Small pieces should adopt quenching, normalizing treatment should be adopted large parts, mainly for the manufacture of high-intensity exercise parts, such as turbine impeller of the compressor piston. Shafts, gears, rack, worm, etc.
