Shandong Liaocheng Grenada Pipe Industry Co., Ltd. specializes Panzhihua, Tianjin, Chengdu, the rule of Steel, Bao Steel Baosteel, Wuxi, Hengyang, Shougang, Anshan Iron and Steel, Handan Iron and Steel. Tangshan Iron and Steel. Other well-known manufacturers of high quality seamless steel pipe and other metal materials, honesty, quality for the letter "is our company's business objectives." Special varieties, complete specifications, "occupy a larger market, Company performance increase gradually expand the scale, in million tons of seamless pipe distribution. I will be with a good reputation and quality products, solid strength, excellent service, low prices and the majority of users to show vision, create brilliant. seamless Compared to other steel and solid steel bar, the same torsional strength in bending, lighter, 20cr precision light pipe factory, it is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts. precision steel in succession advantages of seamless steel tubes, but also has some of its own characteristics. Precision manufacturing annular parts, Liaoyuan precision light pipe, can improve material utilization, 42crmo precision light pipe factory, simplifying the manufacturing process, saving materials and processing time, such as rolling bearings rings, jack sets, has been widely used to manufacture precision steel Precision seamless steel promote the use of savings, improve processing efficiency, reduce the manufacturing processes or equipment investment is important, it can save costs and processing time, 16mn precision bright pipe plant, increase production capacity and material utilization, and help to improve product quality, reduce costs, improve economic efficiency are important. generally require a higher accuracy using precision seamless tube industry, mostly no precision requirements seamless pipe, after all, the same specifications than the price of seamless precision seamless high precision seamless Liaocheng Grenada chemical composition: Carbon C: 0.10 ~ 0.15 Si Si: 0.17 ~ 0.37 Manganese Mn: 1.10 ~ 1.60 Sulfur S: ≤0.035 phosphorus P: ≤0.035 chromium Cr: 0.90 ~ 1.30 Vanadium V: 0.03 ~ 0.06 Mo Mo: 0.32 ~ 0.40 boron B: 0.002 ~ 0.006 precision seamless mechanical properties: Tensile strength σb (MPa): 868 Conditions yield strength σ0.2 (MPa): 713 Elongation δ5 (%): 17 Elongation δ10 (%): 11 Reduction of area ψ (%): 62 impact toughness αku (J / cm2): 5 test Sample size: a sample precision seamless steel heat treatment and microstructure specifications: Heat treatment specifications: 900 ℃ normalizing, 600 ℃ tempered Microstructure: Tempered sorbite tempered bainite + small amount of Liaocheng grid. Swiss precision seamless steel pipe features: 1. high precision outer diameter smaller .2 .3 do small batch production of high precision cold drawn finished, good surface quality .4 .5 steel pipe cross area is more complex and more performance.... location, relatively dense metal.
