Will the stainless steel sewage pump definitely not rust?

I think this question is a stainless steel sewage pump, it will definitely not rust, otherwise it would not be called a stainless steel sewage pump. 

In fact, this is a misunderstanding. Stainless steel sewage pumps can also rust. Why? Here we start with the material of the stainless steel sewage pump.

The so-called stainless steel sewage pump refers to changing the properties of steel after adding chromium and other elements to the steel. For example, 

the molecular structure of steel is more uniform, and a dense oxide protective film is more likely to be formed on the surface of the steel, thereby greatly

 improving the corrosion resistance of stainless steel sewage pumps.

Among stainless steel, due to the different proportions of various filler elements, they are divided into various models. The commonly used stainless steel 

materials for water pumps are divided into ordinary stainless steel, 304 stainless steel, 316 stainless steel, etc. According to the needs of use, the stainless 

steel sewage pump can also provide stainless steel materials treated with special processes, such as: 316L. L is to reduce its carbon content after heat 

treatment to achieve better corrosion resistance.

Here we should say that all metal materials will be corroded and rusted under certain conditions. However, compared with ordinary steel, stainless steel 

can be used in a wider environment, and stainless steel sewage pumps are definitely likely to rust.

So when you buy a sewage pump, you still have to choose a sewage pump that suits you according to your specific actual situation. We met customers and

 saw that the stainless steel sewage pump is very beautiful, then they made sure that it was necessary to have stainless steel. After using it for a while, the 

stainless steel sewage pump had a little rust, and then asked this question, isn’t the stainless steel sewage pump not rust? Why did the ones we bought 

have rust, so I will explain them to you today. If you encounter such a problem in the future, you will know what's going on. Of course, if you have any 

questions about the selection of stainless steel sewage pumps, please contact our Dingfei Pump Industry in time.
