304 stainless steel and 316L stainless steel are both stainless steel models that we often encounter, so which is better between 304 and 316L stainless steel?
1. Different grades
304 and 316L are both stainless steel grades in the American standard, while the Chinese grade 304 is 06cr19NI10, while the 316L Chinese grade is 06Cr17Ni12Mo.
2. Different chemical elements
The nickel content of 304 is 8 nickels, while the nickel content of 316L can reach 10 nickels. In contrast, 316L with 2 more nickels is better than 304 stainless steel in terms of rust resistance and corrosion resistance! And because 316L stainless steel has L, its carbon content is very low. The content of 316L is only 0.03, which is ultra-low carbon compared to 0.08 of 316 stainless steel, so its corrosion resistance is even better!
3. The price is different
The current market price of 304 stainless steel is about 13,500 yuan / ton, while the price of 316L stainless steel plate is 19,000 yuan / ton, and the price difference between the two is 5,000-6,000 yuan / ton. , but if there are relatively high requirements for product performance, 316L stainless steel must be selected.
4. Different corrosion resistance
Because of the different chemical elements and mechanical properties of stainless steel, the corrosion resistance of 316L stainless steel is better than that of 304 stainless steel, and its excellent corrosion resistance is well received by the majority of enterprise users!
