| 精密冷拔管（精拔管）是用 冷拔管无缝管做为原材料进行公差控制和表面光亮加工的一种高精密的钢管材料。 精密冷拔管具有精度高、光洁度高、内壁清洁度好、钢管承受高压无泄漏、冷弯不变形、扩口、压扁无裂缝等特点、能作各种复杂变形及机械加工处理。精密冷拔管的化学成分有碳C、硅Si、锰Mn、硫S、磷P、铬Cr。 Precision cold drawn pipe (precision drawn pipe) is a kind of high precision steel pipe material which uses seamless cold drawn pipe as raw material for tolerance control and surface bright machining. Precision cold drawn pipe has the characteristics of high precision, high finish, good inner wall cleanliness, no leakage under high pressure, no deformation in cold bending, no crack in expanding, flattening, etc., and can be used for various complex deformation and machining treatment. The chemical components of precision cold drawn tube are carbon C, silicon Si, manganese Mn, sulfur s, phosphorus P and chromium CR. |
