What is the difference between 304 and 316 stainless steel, and what are the common stainless steel materials ?

I believe that many people now have stainless steel containers at home. When buying, you must distinguish between 316 stainless steel and 304. Although they are all stainless steel, they are very different. So what is the difference between 316 stainless steel and 304 stainless steel.

What are the differences between 316 stainless steel and 304

1. The difference in use, both 304 and 316 have reached food grade, but 304 stainless steel is usually used in our home appliances and household containers, and 316 stainless steel is generally used in the production of medical equipment and tools. It is enough for our family container to reach 304, so if the merchant says his container is 316, it is fooling you.
2. Corrosion resistance, the corrosion resistance of the two materials of stainless steel is similar, but 316 has added anti-corrosion silver on the basis of 304, so the corrosion resistance of 316 is better when the content of chloride ions is higher.
3. The price difference, 316 stainless steel has silver and nickel added, but 304 stainless steel does not, so the price of 316 stainless steel will be a little higher than that of 304.

What are the common stainless steel materials

1. 201 stainless steel is one of the 300 series stainless steels, which has relatively high acid resistance, alkali resistance, and density.
2. 202 stainless steel is a low-nickel and high-manganese stainless steel material, commonly used in shopping malls or municipal projects.
3. 301 stainless steel is a metastable austenitic stainless steel, which has better rust resistance and a relatively complete austenitic structure.
4. 303 stainless steel is an easy-to-cut stainless and acid-resistant steel that can be used in the production of automatic beds, bolts, and nuts.
5. 304 stainless steel, which has relatively good processing performance and relatively comprehensive performance, is a general-purpose stainless steel.
6.304L stainless steel is called low carbon stainless steel. It has superior comprehensive performance.
7. 316 stainless steel is austenitic stainless steel. It contains Mo element inside. The agent has better high temperature resistance and corrosion resistance. It can be used in pipelines and dyeing equipment.

Advantages of stainless steel

1. Relatively high temperature resistance, 304 and 316 stainless steel are better than ordinary stainless steel, and the highest temperature resistance can reach more than 800 degrees, which is suitable for various places.

2. Anti-corrosion, both 304 and 316 have added chromium elements, the chemical properties are stable, and basically they will not be corroded. Some people use 304 stainless steel as anti-corrosion materials.

3. High toughness, can be processed into different products, and the quality is very good.

4.The lead content is low, and the lead content of 304 and 316 stainless steel is extremely low, and there is no harm to the human body, so it is called food stainless steel

The above is the introduction of the difference between 316 stainless steel and 304, I hope it can give you some reference opinions.
