The higher molybdenum content results in grade 316 possessing increased corrosion resistance. The two most common stainless steel grades are 304 and 316. While type 304 stainless steel seems like a more economical choice, it doesn't have the same resistance to saline and chloride. 316 stainless steel contains molybdenum, but 304 does not. Another difference is that 304-grade stainless steel has a higher melting point than 316-grade stainless steel. Stainless Steel 316. In fact, two of the most widely used stainless steel grades fall within this family: 304 stainless steel and 316 . Still, it doesn't resist chlorides and chemicals as well as marine grade 316 stainless steel does. On the other hand, 316 stainless steel consists of 16% chromium, 10% nickel, and 2% molybdenum. Like many steel alloys, it has a continuous use temperature several times higher than most food making processes will ever require (more than 800C, or 1472F). The key difference is the addition of molybdenum, an alloy which drastically enhances corrosion resistance, especially for more saline or chloride-exposed environments. STAINLESS STEEL 201 VS 304 FOOD GRADE Magnetism. 316 SS: Performs best in temperatures above 843 . is being done in a 304 vs. a 316 stainless steel sink. 2) Properties: the higher molybdenum content results in grade 316 getting increased corrosion resistance. 304 Stainless Steel. For example, 18/8 stainless steel is comprised of 18% chromium and 8% nickel. This difference makes 316 stainless steel more resistant to corrosion compared to 304 stainless steel. 1) Composition: 304 contains 17.5%-19.5% chromium and 8%-10.5% nickel while 316 contains 16.5%-18.5% chromium, 10%-13% nickel and 2%-2.5% molybdenum. Grade 310 stainless steel contains more chromium (24-26%) than Grade 304 (10-20%). The key difference between 304 vs 316 stainless steel that makes them different is the addition of molybdenum, an alloy that drastically enhances corrosion resistance, especially for more saline or chloride-exposed environments. 0.1-3mm dia sphere for example) can be attracted to powerful magnetic separators positioned in the product stream. 304 is an austenite steel and is only slightly responsive to magnetic fields. Often, the manufacturer will mark the stainless-steel part to indicate its grade. For one thing, Inconel is much more expensive than stainless steel alloys.Inconel also has much better corrosion resistance and strength at high temperatures. There are many different types of food-grade stainless steel, each containing different compositions and properties. As 316 contains molybdenum, it has a higher resistance to chemical attack than type 304. Additionally, type 310 contains 19-22% nickel while type 304 only contains 8-10.5% nickel. 316 grade is the second-most common form of stainless steel.
