What Is The Testing Method For Stainless Steel Material Of Corrosion-resistant Submersible Sewage Pump
Oct 07, 2025
We know that stainless steel is a commonly used material for corrosion-resistant submersible sewage pumps. So how can we ensure that the stainless steel material of the purchased corrosion-resistant submersible sewage pump can meet the requirements for use? Below, the editor will tell you a simple and practical method that can help you identify and master this method, so you don't have to worry about being deceived and losing out. The specific testing method for stainless steel material of corrosion-resistant submersible sewage pump is as follows:
The most commonly used materials for stainless steel corrosion-resistant submersible sewage pumps are 201, 304, 316, and 316L. If the requirements are not high, ordinary stainless steel 201 can be used. If the requirements are slightly higher, 304 material can be used. If it is a strong acid, 316 and 316L materials are needed. Can the material of stainless steel submersible sewage pumps meet the requirements for use? How to detect it conveniently?
The stainless steel material detection of corrosion-resistant submersible sewage pumps mainly uses stainless steel rapid determination solution, stainless steel testing solution, and stainless steel identification solution. The material detection of stainless steel submersible sewage pumps is actually to detect the nickel content in stainless steel. By reacting the chemical substances in the solution with the nickel in stainless steel to form a specific colored complex, the approximate nickel content in stainless steel can be determined.
For example, when the nickel content in the tested stainless steel is greater than 8%, the 304 solution will display a color. However, because the nickel content of stainless steel materials such as 316 and 310 is also greater than 8%, using the 304 solution to test 310 and 316 stainless steel will also display a color. Therefore, in order to distinguish between 304, 310, and 316, corresponding chemicals need to be used. The specific method can refer to the instructions for stainless steel identification liquid, so as to detect whether the specific material of the stainless steel corrosion-resistant submersible pump meets the standards.
That's all for the introduction of the stainless steel material testing method for corrosion-resistant submersible sewage pumps. Have you understood and mastered it? Once you master this method, you can check whether the stainless steel material of the corrosion-resistant submersible pump you purchase meets the standards in the future to avoid any losses.
