Distinguish 316 stainless steel:
1. Differentiation of potions.
There are potions for testing 304 stainless steel and 316 stainless steel on the market. If you want to determine whether your stainless steel is made of 316, you can buy 316 stainless steel potions for testing.
The two most commonly used stainless steels 304 and 316 (or 1.4308 and 1.4408 corresponding to German/European standards). The main difference in chemical composition between 316 and 304 is that 316 contains Mo, and it is generally recognized that 316 has better corrosion resistance. , It is more corrosion resistant than 304 in high temperature environment. Therefore, in high-temperature environments, engineers generally choose 316 material components.
2. Detection by spectrometer.
The stainless steel detection spectrometer can detect the element content of the stainless steel wire; as long as it is detected, it can be known whether it is 316 stainless steel wire or not.
3. Salt spray test to detect and distinguish.
The salt spray test time of 201 stainless steel is 24 hours; the salt spray test time of 304 stainless steel is 48 hours; the salt spray test time of 316 stainless steel is 72 hours.
