Our stainless steel capillaries are made of high-quality austenitic stainless steel materials such as 304, 304L, 316, 316L, 321, 310, 310S, 301, 202, and some special alloy materials such as Monel400. Different materials are carefully adapted to different use environments and performance requirements. For example, 304 material has strong versatility and can show good corrosion resistance under normal conditions; while 316L material, with its excellent corrosion resistance, is particularly suitable for fields with strict requirements on corrosion resistance such as chemical industry and medical treatment, and can effectively resist the erosion of various chemical media, ensuring the long-term stable operation of the pipe under complex working conditions.
