Did you know that 304 and 316 are the most popular and widely used types of stainless steel? For instance, if welding is your chief concern for your stainless steel plate or stainless sheet, the 304 Stainless Steel offers durability and strengthening capabilities. This is also a material grade that performs at relatively high temperatures making it ideal for industrial, architectural, and transportation applications. In comparison, the 316 Stainless Steel is optimal for applications requiring more extreme corrosion resistance.
The article contains following:
1,What is different in grade between 304 and 316?
2,What is different in price between 304 and 316?
3,What is different in application between 304 and 316?
The most basic difference between the grades of steel is the presence of molybdenum in stainless 316. Molybdenum is a chemical element used for the strengthening and hardening of steel. Its main function in stainless 316 is to help fight off corrosion from chlorides. 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 increased nickel content and the inclusion of molybdenum makes grade 316 stainless steel a bit costlier than grade 304 per ounce of material. But where grade 316 stainless proves superior is its increased corrosion resistance—particularly against chlorides and chlorinated solutions. This makes grade 316 stainless particularly desirable for applications where exposure to salt or other powerful corrosives is an issue. If you have an application with powerful corrosives or chlorides, the extra cost of stainless 316 is highly recommended. In such applications, 316 stainless will last longer than 304, providing you with extra years of life and usage. If your application uses milder acids or does not contain salt exposure, stainless 304 is perfect. Below we list some common applications for both grades of steel.
The two steel grades are comparable in appearance, chemical makeup and characteristics. Both steels are durable and provide excellent resistance to corrosion and rust. 304 stainless steel is the most versatile and widely used austenitic stainless steel in the world, due to its corrosion resistance. 304 stainless is also cheaper in cost compared to 316, another reason for its popularity and widespread use.
Applications for 304 Stainless Steel:
Auto moldings and trim
Applications for 316 Stainless Steel;
Stainless steel floats
Outdoor electrical enclosures
Not only is there the danger of exposing all your critical electrical components inside, it could cost you a lot to replace when it shorts out. We’re talking parts damage and replacement, repair costs including labor and downtime. I’ve seen some real horror shows when enclosures rust out. It’s not pretty. The good news is we have a simple cost effective solution. We found that by using 316 stainless steel instead of 304 stainless steel on an outdoor enclosure that will be exposed to the elements (like on an oil rig, for example) not only increases the life span of the enclosure but it is much safer to be around.
