冷拔钢管采用材质和用途及特点

2018-12-13 14:36:16 常州市星火铝艺制品有限公司 阅读

冷拔钢管是一种通过冷拔或冷轧工艺生产的高精密度、高光亮度的冷拔无缝钢管。其内外径尺寸可精确至0.2mm以内,在搞弯、抗扭强度相同时,重量较轻,所以广泛用于制造精密机械零件和工程结构。也常用作生产各种常规武器、枪管、炮弹等。

Cold-drawn steel pipe is a kind of cold-drawn seamless steel pipe with high precision and brightness produced by cold-drawn or cold-rolled process. Its inner and outer diameters can be precise to less than 0.2mm. When bending and torsion strength are the same, the weight is lighter, so it is widely used in manufacturing precision mechanical parts and engineering structures. It is also often used in the production of conventional weapons, barrels, shells and so on.

常用材质为10#、20#、35#、45#、20cr、40Cr、20CrMo﹑16mn﹑27simn﹑304﹑201﹑310s﹑优质碳素结构钢。
