Why is 316 stainless steel better than 304 stainless steel?

Nowadays, in addition to our porcelain and glass in life, there are stainless steel. It will not be rusted. It is favored by everyone. 

Do you know that the stainless steel pipe used in our lives is also made of two different stainless steel. One is 304 food grade and one is 316 medical grade. So what is the difference between these two stainless steels? 304 stainless steel and 316 stainless steel which one is better? Anyway, I put it directly in front of Xiaobian, I can't see it, so what is the distinction between actual use? Let's take a look with Xiaobian.

1.304 stainless steel

In fact, the type of stainless steel we use most today. The common stainless steel water pipes, stainless steel spoons, and stainless steel cups in our lives are almost all 304 stainless steel.

As we all know, stainless steel is generally made of iron, and then some metal elements such as carbon, nickel, chromium are added. The quality of stainless steel is generally determined by the content of these rare metals. Stainless steel 304 must contain 18%chromium and 8%nickel to meet the standard, which is usually called food -grade stainless steel. This level of stainless steel is more exposed to acid and alkali, so it has good anti -acid and alkali capacity, and its density is high, and it looks good after polishing.

2.316 stainless steel

Why is 316 stainless steel more expensive than 304 stainless steel? People who don't know may have doubts.

This is actually because 316 stainless steel compared with 304, its composition has a rare metal called molybdenum (MO).

This metal element makes 316 stainless steel more corrosive than 304.

This is why it is generally used in industries such as food processing, machinery, heavy industry, or parts manufacturing in high temperature environments.

3.304 The difference between stainless steel and 316 stainless steel

(1) Consider from the perspective of corrosion

The corrosion resistance of 304 stainless steel fully meets food -level standards and is also a national -certified food -grade stainless steel.

The corrosion resistance of 316 stainless steel is stronger than that of 304 stainless steel. It can also be said that 316 stainless steel is a higher -grade food -grade stainless steel than 304 stainless steel. In daily life, stainless steel products choose 316 stainless steel. it is good.

(2) Consider from the perspective of price

The price of 316 stainless steel products is higher than the price of 304 stainless steel products, but it feels better.

I personally think that the use of stainless steel products is very high. You can choose 316 stainless steel products, and the requirements for the use of 304 stainless steel can also be selected.

In general, 316 stainless steel is better than 304 stainless steel, because the strength and flexion and extension of 304 and 316 stainless steel are equal, but the wear resistance of 316 stainless steel is better than 304 stainless steel, because the hardness of 316 stainless steel is slightly higher than 304, they They are all Austeen stainless steel, and the corrosion resistance of 316 stainless steel is also better than 304 stainless steel. 316 stainless steel's main uses include pulp and papermaking equipment heat exchangers, dyeing equipment, film flushing equipment, pipelines, and exterior materials for buildings in coastal areas, so 316 stainless steel is better than 304 stainless steel.
