Difference between 304 and 316 stainless steel



Difference between 304 and 316 stainless steel

I believe a lot of people now have stainless steel containers in their homes. Why are stainless steel containers preferred by so many people because they do not rust and are very resistant to high temperatures. It is also very convenient to clean, but when buying one must distinguish between stainless steel 316 and 304. Although they are all made of stainless steel, the difference is very big. Today, I am going to present to you what is the difference between stainless steel 316 and stainless steel 304?

304 vs 316 stainless steel pipe

Difference between stainless steel 304 and 316:

1. The difference in use
Both 304 and 316 have achieved food grade, but 304 stainless steel is generally used in our home appliances and household containers, and 316 stainless steel is generally used for the production of medical equipment tools. . Our family container is enough to reach 304, so if the merchant says their container is 316, they are cheating on you.

2. Corrosion resistance
304 steel is resistant to corrosion by sulfuric acid, phosphoric acid, potassium acid, urea, etc.

316 has increased corrosion resistance based on 304, which can greatly improve its resistance to intergranular corrosion, oxide stress corrosion, and reduce the tendency to heat during welding. It also has good corrosion resistance to aluminum chloride. . Therefore, the corrosion resistance of 316 is better when the content of chloride ions is higher. Due to the addition of molybdenum element, 316 stainless steel has a special corrosion resistant structure and higher resistance to chloride corrosion. It is also used as “marine steel”.

3. The price difference
316 added molybdenum and nickel so the price is a bit higher than 304.

Advantages of stainless steel pipe:

1. Relatively high temperature resistance, 304 and 316 stainless steels are better than ordinary stainless steel, and the high temperature resistance can reach up to 800 degrees, which is suitable for various places.
2. Anti-corrosion. The 304 and 316 both added chromium which has stable chemical properties and will basically not corrode. Some people use 304 stainless steel as anti-corrosion materials.
3. High tenacity, can be made into different products and the quality is very good.
4. Low lead content. The lead content of 304 and 316 stainless steel is extremely low and does not cause any harm to human body, which is why it is called food grade stainless steel.

How to prevent rusting of stainless steel?

Generally, 304 and 316 stainless steels do not rust easily. Be careful not to soak the stainless steel container in salt water for a long time. It will not rust. If stainless steel encounters chloride ions, it will cause corrosion, so try to avoid contact with salt, sea water, etc.
