Shandong Liaocheng Grenada precision seamless 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 stretch Long rate δ10 (%): 11 Reduction of ψ (%): 62 impact toughness αku (J / cm2): 5 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. Shandong Liaocheng precision seamless Grenada characteristics: 1. an outer diameter smaller. High precision can do small batch production. 3. cold drawn finished high accuracy, good surface quality. 4 Steel Cross area more complex. 5 steel pipe superior performance, the 45 # precision steel plant, the metal is relatively dense. Pipe Co., Ltd. Shandong Liaocheng Grenada is perforated, thermal expansion, hot-rolled, finishing, cold drawn sales, the implementation of the principle of corporate diversification strategy, 20 # precision steel plant, the company covers an area of ??100 acres, has a staff of 300 people (including 10 senior engineers, professional technicians 30, hired experts 5). Hot rolling mill 2, precision steel pipe manufacturers, can produce diameter 25-219mm wall thickness 3-40mm seamless steel tubes. Drawing unit 6 sets, can produce diameter 6-89mm wall thickness of 1-20mm of fine drawing small-caliber seamless steel pipe. Unit 2 finishing mill LG20, LG30 unit 2, LG50 unit 2, LG60 LG120 unit 2 unit 1 annual production size φ6-219 × 1-30mm diameter precision seamless steel precision seamless tube, precision light pipe. Precision Tube is a drawn or cold rolling through the production of high-precision, high brightness of seamless steel tubes. Its inner diameter size can be accurate to within 0.2mm, engaged in bending, torsional strength of the same, Zhaoqing precision steel, lighter, so it is widely used in the manufacture of precision mechanical parts and engineering structures. Also used in the production of conventional weapons, the barrel, shells and so on. Precision steel seamless tube production processes and regular, as is more the channel last pickling cold rolling process. Process precision steel tube - test - peeling - test - heating - piercing - pickling passivation - grinding - dry lubricant - cold - to oil - the first cut - Inspection - Identification - product packaging. Company spirit: innovation is an eternal theme, beyond the relentless pursuit. Mission: credibility first, honesty. We will take reasonable price, good reputation and solid strength, quality products, the most attentive service, to serve the new and old customers.
