1. Identification of shoddy steel precision tubes prone to folding. Various fold folding cylinder tube steel profiles formed on the surface, this defect often throughout the product vertical. The reason is due to shoddy manufacturers of folding the pursuit of high efficiency, reduction is too large, resulting in the ears of the hydraulic cylinder tube, it creates a rolling when folded down, it will crack when folded products bending, the strength of steel big drop. 2. Shoddy steel exterior often Pock phenomenon. Pock is caused due to a serious groove worn steel surface uneven irregular defects. Due to the pursuit of profit and shoddy steel pipe manufacturers, often the most excessive rolling groove. 3. Shoddy steel surface is easy to produce scarring. There are two reasons: (1). Shoddy steel material uneven impurities. (2). Shoddy material manufacturers guides poorly equipped, easy to stick steel, easy to produce scarring after the roll bite of these impurities. 4. Shoddy steel pipe diameter size fluctuations due; l, steel surface temperature instability of yin and yang. 2, the non-uniform composition of the steel. 3, due to poor equipment, low-intensity ground, rolling big bounce. There will be a large change in the same week, so easy to produce steel discontinuity break. 5 cylinder tube. Inferior surface material easy to crack because it is blank billet, billet cooling over standard cylinder tube, process due to thermal stress, cracks, crack 6. After rolling, there is a loose packing. Side of the oval. Chemical composition of precision light tubes and a variety of different materials comparison: carbon C, silicon Si, manganese Mn, S, phosphorus P, chromium Cr. 10 # 0.07 ~ 0.13 0.17 ~ 0.37 0.35 ~ 0.65 ≤0.035 ≤0.035 20 # 0.17 ~ 0.23 0.17 ~ 0.37 0.35 ~ 0.65 ≤0.035 ≤0.035 35 # 0.32 ~ 0.39 0.17 ~ 0.37 0.35 ~ 0.65 ≤0.035 ≤0.035 45 # 0.42 ~ 0.50 0.17 ~ 0.37 0.50 ~ 0.80 ≤0.035 ≤0.035 40cr 0.37 ~ 0.44 0.17 ~ 0.37 0.50 ~ 0.80 ≤0.035 ≤0.035 0.08 ~ 1.10 cylinder fittings, Jinan cylinder tube, pipe industry by virtue virtue Liaocheng Industry Co., Ltd.
