316 stainless steel cost comparison which is more costly. It offers the standard corrosion resistance formability strength and easy maintenance for which stainless is known.
For outdoor furnishings like rails and bollards stainless steel is an ideal corrosion resistant material but it will only withstand long term exposure if the grade is appropriate for its environment.
Stainless steel 304 vs 316. Stainless 316 contains more nickel than stainless 304 while 304 contains more chromium than 316. Stainless 304 usually consists of 18 chromium and 8 nickel. Stainless 316 is made up of 16 chromium 10 nickel and 2 molybdenum.
The two steel grades are comparable in appearance chemical makeup and characteristics. After analyzing chemical composition makeup corrosion resistance cost and suitable applications the key difference between 304 and 316 stainless steel is that 316 grade has better corrosion resistance thanks to addition of molybdenum than 304 especially for chloride applications and last longer service life. 304 grade is cost effective choice and performs well for general service selecting which type depend on your application and environment.
What s the difference between 304 and 316 stainless steel. The simple answer is 304 contains 18 chromium and 8 nickel while 316 contains 16 chromium 10 nickel and 2 molybdenum. 316 stainless steel contains molybdenum.
304 stainless steel does not. For outdoor furnishings like rails and bollards stainless steel is an ideal corrosion resistant material but it will only withstand long term exposure if the grade is appropriate for its environment. 304 is an economical and practical choice for most environments but it doesn t have the chloride resistance of 316.
Based on the density the higher density stainless steel has the more weight it will get that is why 304 stainless steel material is somewhat lighter than 316 stainless steel upon the same condition. 304 vs 316 stainless steel. The main difference between 304 vs 316 stainless steel is the composition and corrosion resistance ss304 doesn t contain molybdenum while ss316 contains 2 3 molybdenum.
The addition of molybdenum provides pitting resistance in phosphoric acid acetic acid and dilute chloride solutions and provides corrosion resistance in sulfurous acid. A major difference between 304 and 316 stainless steel is the chemical composition with 316 containing a significant amount of molybdenum. Typically 2 to 3 percent by weight vs only trace amounts found in 304.
The higher molybdenum content results in grade 316 possessing increased corrosion resistance. When it comes to 316 stainless steel you can expect better corrosion and pitting resistance to chlorides than 304 stainless steel and higher levels of strength at elevated temperatures. This is due in part to the addition of molybdenum.
The benefits of 316 stainless steel. Most stainless steel ordered around the world is grade 304. It offers the standard corrosion resistance formability strength and easy maintenance for which stainless is known.
While 316 comes in second in terms of quantities sold it offers vastly superior corrosion resistance to chlorides and acids. 316 stainless steel cost comparison which is more costly. Stainless steel is one of the least costly material options in the metal industries.
But the upfront cost of 316 is a little higher than 304. 316 stainless steel costs 20 to 30 percent more than 304.
