山东大鼎金属材料有限公司From a positive point of view, the market is still in weak integration. Price adjustment policies, as the weather warms, are slowly reviving the industry; if raw materials do not show too much volatility, it is difficult to fall again, because the market is less profitable and expected to be higher, so alloy tubes will be very strong after a tentative pull on the market.
山东大鼎金属材料有限公司Precision steel pipe refers to high precision steel pipe whose wall thickness and inside and outside diameter can be controlled within the tolerance range of the steel wire. This kind of steel pipe is different from the outside surface of common hot-rolled seamless steel pipe and cold-drawn seamless steel pipe. Hot-rolled, precision steel tube surface and inner diameter smooth, color and stainless steel, the internal and external surface due to manufacturing reasons are with a layer of oil size precision, good surface quality seamless steel tube is called precision steel tube. Precision tube is a high density and high brightness seamless steel tube produced by cold drawing or cold rolling process. 山东大鼎钢管厂精密无缝钢管均执行标准：GB3639-2000冷轧精密无缝钢管GB/T8162-2008结构用无缝管、GB/T8163-2008流体精密无缝管、GB/T3087-2008低中压锅炉精密管、GB/T5310-2008高压锅炉无缝管、GB/T17396-1999液压支柱精密钢管、GB/T6479-2000化肥专用合金管、GB/T3088-1982汽车半轴套管用无缝钢管、GB/T3093-2002柴油机用高压油管、GB/T8713-1988液压和气动缸筒用精密无缝钢管。精密钢管是近年来出现的一种产品。这主要是由于内孔和外壁的严格公差和粗糙度。
The vacuum carburizing temperature is generally higher than that of ordinary gas carburizing. Carburizing and diffusion are often used at 920~1040 C. As shown, there are two stages: pulse ventilation, stop gas, multi-stage carburizing and diffusion. The effect is better. Vacuum carburized layer is formed faster than ordinary gas, liquid and solid carburized layer because of its high temperature, especially its clean surface and high activity. If the carburized layer needs 1 millimeters, it will take 927 hours and 1 hours at 1033 degrees Celsius, only 5 hours.
Precision steel pipe has the advantages of no oxide layer on the inner and outer walls, high pressure, no leakage, high precision, high finish, small cold bending deformation, high flatness, no cracks and so on. It is mainly used to produce pneumatic or hydraulic components. As a cylinder or an oil cylinder, it can be a seamless tube. The chemical composition of cold drawn precision steel pipe
