316 stainless steel and 304 which good?

We will often use stainless steel in our home life, stainless steel rice bowl, stainless steel water cup, and even stainless steel cabinet table.

304 stainless steel

First of all, I want to introduce 304 stainless steel, all the main components of stainless steel are iron, a few components of carbon, nickel, chromium.

Because the composition of stainless steel is different, corrosion resistance is different, the name is naturally different.

304 stainless steel, which must contain 18% chromium and 8% nickel, is a food-grade stainless steel that is more than adequate for household use.


316 stainless steel

316 stainless steel added MO element, corrosion resistance and acid resistance is better, widely used in medicine and industry, the price is more expensive, the general family will not use 316 stainless steel.


304 stainless steel and 316 which good?

1. Acid and alkali resistance

The acid and alkali resistance of 316 stainless steel is definitely better than 304 stainless steel. The main reason is that the content of the two components is different. The MO element content of 316 stainless steel is higher and the corrosion resistance of MO is strong, so the corrosion resistance of 316 stainless steel is better than ordinary stainless steel.

Step 2: Price

The price of 304 stainless steel is lower than 316 stainless steel, it is the type of stainless steel that people can afford to use at home. 316 stainless steel because of different composition content, so the price can be twice of 304 stainless steel.

3. Use environment

The above mentioned 304 stainless steel is food grade stainless steel, so it is often used to make kettles, chopsticks, rice bowls.

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 stainless steel?

Whether 304 stainless steel or 316 stainless steel on the market will always appear some fake, so stainless steel true and false how to distinguish?

1. Use a special test solution

To test the authenticity of stainless steel, buy a bottle of stainless steel test liquid. When the test liquid drops are placed on the surface of stainless steel, there will be color changes. You can distinguish which grade of stainless steel is represented by different colors through the instructions.

It should be noted that if there is a coating on the surface of stainless steel, the coating needs to be scraped off and tested again.

2. Look at the nameplate

You can see the first and second pictures of my article. The regular 316 and 304 stainless steel are marked with steel marks. If there is no steel marks in the stainless steel purchased, it is probably a fake.

304 and 316 stainless steel can not say who is good who is bad, 316 corrosion resistance is better, often used in the production of medical equipment and industrial equipment.

304 stainless steel is food grade, often used to make bowls, chopsticks, kettles.
