Which is better, 316 stainless steel or 304?
In home life, we often use stainless steel, stainless steel rice bowls, stainless steel water cups, and even stainless steel cabinet countertops. But don't think that there is only one type of stainless steel. In fact, stainless steel is also divided into 316 and 304.
So which is better, 316 or 304 stainless steel? Let me tell you below!
304 stainless steel
First of all, I would like to introduce 304 stainless steel. The main component of all stainless steel is iron, and a small part of it is carbon, nickel, and chromium.
Because the composition of stainless steel is different, the corrosion resistance is also different, and the name is naturally different.
304 stainless steel must contain 18% chromium and 8% nickel. 304 stainless steel is food-grade stainless steel, which is more than enough for household use.
316 stainless steel
let me talk about 316 stainless steel. The reason why the names of stainless steel are different is because the composition of stainless steel is different.
316 stainless steel is added with MO element, which has better corrosion resistance and acid resistance. It is widely used in medicine and industry, and the price is relatively expensive. 316 stainless steel is not used in general households.
Acid and alkali resistance
I think 316 and 304 stainless steel can't be said to be good or bad. I will analyze these two stainless steels from three aspects:
1. Acid and alkali resistance
The acid and alkali resistance of 316 stainless steel is definitely better than that of 304 stainless steel. The main reason is that the content of the two components is different. The content of MO element in 316 stainless steel is higher, and the corrosion resistance of MO is very strong. Therefore, the corrosion resistance of 316 stainless steel is better than that of ordinary stainless steel. Stainless steel is better.
The price of 304 stainless steel is lower than that of 316 stainless steel, which is the type of stainless steel that ordinary people can afford at home. The price of 316 stainless steel can be twice that of 304 stainless steel because of the different composition content.
3. Use environment
As mentioned above, 304 stainless steel is food-grade stainless steel, so it is often used to make kettles, chopsticks, rice bowls, and water pumps.
316 stainless steel is often used to make medical equipment or industrial equipment because of its strong corrosion resistance.
How to distinguish the true and false of stainless steel?
Whether it is 304 stainless steel or 316 stainless steel, there will always be some fakes on the market, so how to distinguish the true and false stainless steel?
Use a special test solution
Look at the nameplate
1. Use a special test solution
If you want to test the authenticity of stainless steel, you can buy a bottle of stainless steel test solution. When the test liquid is dropped on the surface of stainless steel, there will be a color change. You can tell which grade of stainless steel different colors represent through the instructions.
It should be noted that if there is a coating on the surface of the stainless steel, the coating needs to be scraped off before testing.
2. Look at the nameplate
Regular 316 and 304 stainless steels are marked with steel seals. For details, please ask Dolay Pump after-sales service.
