The difference between 304 and 316 stainless steel plates

   What is the difference between 304 and 316 stainless steel plates? In fact, 304 stainless steel plate and 316 stainless steel plate both belong to 300 series austenitic stainless steel, and they are also stainless steel decorative plates that are often used in life. Different types of boards are bound to have different properties. If you think you can tell them apart with the naked eye, you are too naive.

   Although there is not much difference in appearance between 304 and 316 stainless steel plates, we can distinguish the difference between the two in terms of composition. The 304 grade is 0Cr18Ni9 and the 316 grade is 0Cr17Ni12Mo2. It can be seen that the 316 stainless steel plate contains Mo element, which can make the 316 stainless steel plate have much better performance in high temperature resistance. If it is in a high temperature environment, most people will choose 316 stainless steel plates, so that the stability of the product can be better exerted.

   The chromium content is reduced and the nickel content is increased in the 316 stainless steel plate, which enhances its corrosion resistance. Especially it can be used in seawater or chemical environments, but the cost of 316 stainless steel plates is also higher than that of 304. Generally, 304 stainless steel plates are more economical for household use.

   The most direct way is to use potion to distinguish. Just drop a little on the stainless steel plate, and the potion will immediately react chemically with the stainless steel plate. Through the different colors of the reaction, you can clearly determine whether it is a 304 or 316 stainless steel plate.
