Specification

In fact, different kinds of stainless steel are only added to it with different alloying elements, so as to have some of the characteristics we need, 316 stainless steel is the same, when 304 stainless steel some properties can not meet our needs 316 was developed. Xiyouwo stainless steel mainly does 201 and 304 stainless steel pipe, what is the difference between 304 and 316, let's analyze it together today!

1. Grade issues. 304L and 316L are extended in 304 and 316, respectively, and each grade is as follows:

304 is 06Cr19Ni10, 304L is 00Cr19Ni10;

316 is 0Cr17Ni12Mo2, 316L is 00Cr17Ni14Mo2.

3. Food grade issues.

People often ask if 304 is food grade? In fact, according to the material, the material content of 304 has reached food grade, and the common food grade materials in the market are about three: 304, 316 and 430 stainless steel. 304 is commonly found in our household small household appliances or water cups, 316 is used in medical equipment, and 430 is often used as stainless steel for knives. But here also to clarify a concept, not to say that the material is food grade he is food grade, but also includes whether the manufacturing and other links meet the food grade standard, just like Xiyouwo is to do decorative stainless steel pipes, and there will be another stainless steel pipe factory is specialized in the production of food grade stainless steel water pipes, the required process links are different.

4. Corrosion resistance problem.

316 stainless steel is 304 stainless steel, and stainless steel produced by adding some more molybdenum to the resistance to pitting corrosion. In various types of water quality (distilled water, drinking water, river water, boiler water, etc.), the corrosion resistance of 304 stainless steel and 316 stainless steel is almost the same, but when the content of chloride ions in the medium is very high, 316 stainless steel is more suitable.

5. Price issues.

Due to the molybdenum and nickel elements added to 316, 316 stainless steel is more expensive than 304 stainless steel.
