Stainless Steel Pipe-Encyclopedia

304 and 316L stainless steel materials are the only health materials that can be implanted into human body, so for water supply pipes, stainless steel pipes are the most beneficial to health. In the immersion water test, all the indicators meet the requirements of the relevant national drinking water standards. Stainless steel pipeline has smooth inner wall, no fouling, no bacterial contamination, anti-bacterial, anti-seismic, anti-tension, high pressure and high temperature resistance, no need to worry about water quality, and can prevent secondary pollution of water.Thin wall stainless steel water supply pipe is recognized as one of the best pipes with comprehensive properties

304不锈钢水管的加工工艺

2019/8/20 13:12:45

现如今，社会经济发展迅速，说起304不锈钢水管，我们大家应该都不会觉得陌生，因为304不锈钢水管在我们的日常生活中应用非常广泛。我们都知道，304不锈钢水管常常用于制作要求良好综合性能(耐腐蚀和成型性)的设备和机件。下面就一起来看看304不锈钢水管有哪些加工工艺吧。

1.热处理工艺

304不锈钢管的固溶处理温度为1080-1100℃，冷却方式为水冷或空冷。冷加工中间退火温度多在850-970℃，保温一定时间后水冷。经固溶处理后钢的组织为奥氏体组织，有时也存在少量铁素体。

2 焊接

304不锈钢管抑制焊接时的碳化物析出，可采用通用的方法进行焊接。手工电弧焊，含碳0.04%-0.06%的薄截面尺寸的304不锈钢可采用奥002焊条，焊后可不产生晶间腐蚀倾向，对于厚截面尺，要保持焊后的耐晶间腐蚀性能，需进行焊后热处理，若不热处理，应改为304L不锈钢或稳定型奥氏体不锈钢。

3.冷成型性能

304不锈钢薄板在应用过程中，常常用于冷成型操作。其冷成型性能是衡量能否顺利成型和成品率高低的重要技术指标。影响304不锈钢的冷成型因素较多，也很复杂。就其金属学因素来讲主要是钢的成分，即铬当量和镍当量之比，其常规拉伸性能中的延伸率是一个重要的表征指标。为了获得良好的冷成型性能，应控制钢中的铬当量和镍当量的比值处于一个适当的范围。

4.应用

食品用设备，一般化工设备，原子能工业用装置部件等，均被广泛应用。适于深冲件和输酸管道、容器等。车辆、汽车零件盒家用器具也都采用该钢种。它是奥氏体不锈钢中生产和用量最多的钢，用于生产薄壁件、输酸管道及结构件等。也经常作焊接铬镍不锈钢和不锈钢的芯材，非磁性部件以及低温环境下使用的部件等。

以上就是304不锈钢水管的主要加工工艺，不知道大家清楚了吗?
