山东大鼎金属材料有限公司Bearing steel pipe is a common rolling bearing ring made of hot rolled or cold drawn seamless steel pipe. The outer diameter of the steel pipe is 25-180 3.5-20mm, and it is divided into two Bearing steel is required to have high hardness and wear resistance, as well as high performance limit, because bearing bearings bear a lot of pressure and friction at work. The uniformity of chemical composition, the content and distribution of non-metallic inclusions and the distribution of carbides in bearing steel are strictly required. It is one of the most stringent steel grades in all steel production.

The popularization and application of high-precision pipes saves steel, improves processing efficiency and saves energy. The so-called high-precision cold-drawn pipe refers to the internal and external diameter precision (tolerance range) is strict, good surface finish, good roundness, uniform wall thickness of cold-drawn pipe. The main technical indexes of the high precision cold drawn tube produced by this technology reach the expected goal. Details are shown in the following table: the main technical indicators and the standard control table items have actually reached the GB8713-88 ISO4394 internal diameter tolerance H8 H9 H8 H8 H8 H8 H8 H8 H8 H8 H9 H9 H10 straightness 0.3 > 0.5/1000B wall thickness deviation roundness汽车半轴套管用无缝钢管（GB3088-82）是制造汽车半轴套管及驱动桥桥壳轴管用的优质碳素结构钢和合金结构钢热轧无缝钢管。德威花园城一期占地约 这是它的柴油机用高压油管（GB3093-86）是制造柴油机喷射系统高压管用的冷拔无缝钢管。精密管或冷轧精密无缝管(GB3639-2000)是机械结构和液压设备用尺寸精度高、表面光洁度好的冷拔或冷轧精密无缝管。高精度精密管是一种新型的高技术节能产品。
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
