304 Vs 316 Stainless Steel Composition

However 304 is a bit more pliable making it ideal for applications where flexibility is desired.

304 vs 316 stainless steel composition.

Just like standard steel stainless. All steels have the same basic iron and carbon composition but stainless steel also contains a healthy dose of chromium the alloy that gives stainless steel its famous corrosion resistance. Ss 317 prove to be a good material in heat exchanger manufacture because it resists galvanic corrosion between the plates and the frame of the heat exchanger in a far better way than ss 304 and ss 316. Stainless 316 contains more nickel than stainless 304 while 304 contains more chromium than 316.

The addition of molybdenum provides pitting resistance in phosphoric acid acetic acid and dilute chloride solutions and provides corrosion resistance in sulfurous acid. Both are non magnetic austenitic and non hardenable through heat treatment. Each of these stainless steel grades will resists corrosion are quite durable and are easily formed and fabricated. The difference in their structure is primarily the addition of molybdenum to 316.

Stainless steel 316 applications some of the common applications of grade 304 are marine parts. In grade 316 the primary differentiator is the material composition i e chromium 16 nickel 10 and 2 molybdenum. In 316 the addition of molybdenum provides more corrosion resistance than you ll find in 304. 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.

Molybdenum is a chemical element used for the strengthening and hardening of steel. The metallic samples of both ss304 and ss316 both are 50 mm thick are being tested in chemical lab and mechanical labs on. Ss 317 is most expensive among them whereas ss 316 is slightly expensive than ss 304. One can easily conclude by reading the table below that ss 317 is nearly 20.

Ss316 has only difference in molybdenum content which enables it corrosion protective in saline environments. Its main function in stainless 316 is to help fight off corrosion from chlorides. Type 304 contains 18 20 chromium and 8 12 nickel as well as a maximum of 0 08 carbon. 91 22 61905600 100 lines email.

Stainless 304 usually consists of 18 chromium and 8 nickel. Type 316 has a similar composition with 16 18 chromium 10 14 nickel and 2 molybdenum. Outwardly 304 stainless steel and 316 stainless steel look very similar. Stainless 316 is made up of 16 chromium 10 nickel and 2 molybdenum.

304 vs 316 stainless steel. The trend in pren pitting resistance equivalent number values also depicts the same superiority of ss 317 over ss 304 and ss 316. 304 and 316 chemical compostion comparison max. Hence due the increased nickel content and the inclusion of molybdenum makes grade 316 stainless steel a bit costlier than grade 304 stainless steel per ounce of material.

As a matter of fact material composition is one of the keys to understanding the differences between 304 and 316. The key difference between 304 and 316 stainless steel in chemical composition is molybdenum element 316 haves 2 3 of it however 304 does not have this is the most important factor to decide their use range both grades have similar proportion of other alloys.
