The biggest difference between 304 and 316 stainless steel lies in the chemical composition. Due to the molybdenum in the steel, the overall performance of this steel is better than 310 and 304 stainless steel. 316L's lower carbon content imparts even better corrosion resistance than 316. The only downside to 304 stainless steel is that it slowly corrodes and will eventually show signs of wear and tear. That's why it is used in wheel covers, electrical enclosures, and general steel pipes. Like 304, the 316 formula does not require post-weld annealing. The main difference between 304 vs 316 stainless steel is that 304 does not contain molybdenum, while 316 contains 2-3% molybdenum and less chromium and more nickel. Stainless-steel piping can be cost-effective for potable water use. The most popular 304 grade stainless contains 18% chromium and 8% nickel though other alloys exist within the same grade. While grade 304 stainless steel is fine for most other applications, type 304 stainless steel is cheaper and easier to fabricate. 316L stainless steel is almost identical to 316. As stated in an AK Steel data sheet for grade 316 stainless steel, the melting range of 316 SS is 2,500 F - 2,550 F (1,371 C - 1,399 C), roughly 50 to 100 degrees Fahrenheit lower than the melting point of grade 304 stainless. Stainless steel 304 is the most widely ordered stainless steel grade in the world. Addition of molybdenum increases corrosion resistance of 316 stainless steel, especially against pitting and crevice corrosion in chloride environments. They have a very high 95% of their average alloy composition in common. 304L can, therefore, be used "as welded" in severe corrosion environments, and it eliminates the need for annealing. Especially in chloride environments it has great resistance to pitting and crevice corrosion. Skip to main content.
