No stainless steel can guarantee that it will never rust. It's just that when we use it, we choose the appropriate scenario based on the specific material. In a sewage treatment plant, the first impression is whether stainless steel pipes cannot be used due to the special environment. In fact, stainless steel pipe guardrails can be used in sewage treatment plants, and the main materials used are304.

　　Stainless steel guardrail
　　Although the environment is special, the guardrails made generally do not come into direct contact with sewage, so the corrosive impact caused will be relatively small. In addition304The corrosion resistance of stainless steel pipes themselves is relatively good201The material is better, although not316It has good performance, but considering the material cost comprehensively, it is generally used304The use of guardrails in sewage treatment plants will be more widespread.

　　The effect of stainless steel pipes can really be different when choosing the appropriate material and specification according to their specific uses.
