What is the difference between 304 stainless steel and 316L stainless steel?
304 stainless steel, also known as 0Cr18Ni9, has a chemical composition that includes: Carbon (C) ≤ 0.08%, Silicon (Si) ≤ 1.00%, Manganese (Mn) ≤ 2.00%, Sulfur (S) ≤ 0.030%, Phosphorus (P) ≤ 0.035%, Chromium (Cr) between 17.00% and 19.00%, and Nickel (Ni) between 8.00% and 11.00%. It is a widely used austenitic stainless steel known for its good corrosion resistance in general environments.
On the other hand, 316L stainless steel, which is also referred to as 00Cr17Ni14Mo2, has a slightly different composition. It contains: Carbon (C) ≤ 0.030%, Silicon (Si) ≤ 1.00%, Manganese (Mn) ≤ 2.00%, Sulfur (S) ≤ 0.030%, Phosphorus (P) ≤ 0.045%, Chromium (Cr) between 16.00% and 18.00%, Nickel (Ni) between 10.00% and 14.00%, and Molybdenum (Mo) between 2.00% and 3.00%. The addition of molybdenum makes 316L more resistant to pitting corrosion, especially in chloride-rich environments like seawater.
The key differences between 304 and 316L are the lower carbon content in 316L (which reduces the risk of intergranular corrosion) and the presence of molybdenum, which enhances corrosion resistance. These properties make 316L more suitable for harsher or more corrosive conditions than 304. Choosing the right type depends on the specific application and environmental factors involved. lithium batteries,lithium ion battery,lithium batteries for sale,batteries,lifepo4 batteries,li ion batteries Jiangyin Haoxuan Technology Co., Ltd. , https://www.haoxuan-tech.com
