What’s the difference between 304 and 316 stainless steel

Posted:2016/8/11 4:59:42

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. The molybdenum is added to help resist corrosion to chlorides.

304 stainless steel Description

Type 304 (18-8) is an austenitic steel possessing a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon. It is a nonmagnetic steel which cannot be hardened by heat treatment, but instead. must be cold worked to obtain higher tensile strengths.

316 stainless steel Description

For severe environments. Of course, there are many industrial processes that require a higher level of resistance to corrosion than Type 304 can offer. For these applications, Type 316 is the answer.

Type 316 is also austenitic, non-magnetic, and thermally nonhardenable stainless steel like Type 304. The carbon content is held to 0.08% maximum, while the nickel content is increased slightly. What distinguishes Type 316 from Type 304 is the addition of molybdenum up to a maximum of 3%.


Type Analysis of Stainless Type 316:

Carbon

0.08% max.

Silicon

1.00% max.

Manganese

2.00% max.

Chromium

16.00-18.00%

Phosphorus

0.045% max.

Nickel

10.00-14.00%

Sulfur

0.030% max.

Molybdenum

2.00-3.00%

How do you know you’re getting 316 stainless steel instead of 304 stainless steel

We make sure we get one with every shipment we receive at Nema Enclosures so that we can assure our customers that the enclosure and its parts are constructed of the exact stainless steel material, as specified and ordered.Some small parts such as clamps and mounting feet, constructed of 316 stainless steel are specifically marked, in this case a number 6 within a circle.

What is Type 304 stainless steel and what’s it used for

Type 304, with its chromium-nickel content and low carbon, is the most versatile and widely used of the austenitic stainless steels.Type 304 stainless steelsare used in corrosion resistant electrical enclosures, auto molding and trim, wheel covers, kitchen equipment, hose clamps, exhaust manifolds, stainless hardware, storage tanks, pressure vessels and piping.

What is Type 316 stainless steel and what’s it used for

Type 316 stainless steel is an austenitic chromium-nickel stainless and heat-resisting steel with superior corrosion resistance as compared to other chromium-nickel steels when exposed to many types of chemical corrodents such as sea water, brine solutions, and the like.
