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.

山东大鼎钢管厂The precision seamless steel tube is a seamless steel tube with high precision and high brightness produced by cold drawing or cold rolling. The inside and outside diameters can be refined, and the bending strength and torsional strength are the same, and the weight is light. Precision seamless steel pipe is used for precision mechanical structure, bearing hydraulic, mechanical processing, hydraulic equipment, steel sleeve.山东大鼎金属材料有限公司生产的无缝钢管广泛用于汽车、摩托车、电动汽车、石化、电力、船舶、航天、轴承、气动元件、中低压锅炉无缝钢管。精密钢管由于具有内外壁无氧化层、高压无泄漏、精度高、精度高等优点，主要用于生产气动或液压元件，如气缸或气缸等无缝或焊接产品。没有冷弯变形，平整和无裂纹。精密钢管主要生产10、20、35、45、40cr、42CrMo级钢管等精密无缝钢管也可咨询供应。常用材料：10_、20_、35_、45_、20G、16Mn、Q345B、27SiMn 35CrMo、42CrMo、40Mn2、20Cr、40Cr、10CrMo910、15CrMo、12Cr1MoV、15CrMoG、12Cr1MoVG、T91、1Cr5Mo等。
