Type 316/316L Stainless Steel Wire

Similar in composition to Type 302, Type 316 stainless steel wire has a slightly higher nickel content and 2-2.50% molybdenum, which gives this alloy better corrosion resistance. Type 316's tensile strength is 10-15% lower than Type 302, and it is slightly less magnetic in the spring temper than Type 302. Thanks to its superior cold working properties, it can be utilized for severe cold forming operations and exhibits short time tensile and creep strength properties at elevated temperatures. Gibbs Interwire Type 316 stainless steel wire is coated for coiling and is available in the range of 0.015" - 0.625", conforming to ASTM A 313. Nickel-coated wires are available on application within the size range of 0.007" to 0.130".

Why is G316 Stainless Steel the Best Material for Wire Balustrades?

It's pretty simple really—Stainless Steel lasts a very long time and looks awesome.

Why is it Worth Using Marine Grade Stainless Steel?

For severe environments such as high exposure to the elements, chemicals, and solvents, one of the most challenging is a marine or coastal location. Stainless Steel Wire Rope is available in various grades, and the two you will most often encounter are 304 and 316. Both grades can be accurately termed 'Stainless Steel' and share certain characteristics, but the differences are crucial.

What is the Difference Between G304 and G316 Stainless Steel Wire and Fittings?

Type 316 (or Marine Grade or G316) is also austenitic, non-magnetic, and thermally non-hardenable like Type 304. The carbon content is maintained at a maximum of 0.08%, while the nickel content is slightly increased. The key difference is the addition of molybdenum, up to a maximum of 3%. To put it simply, 316 is a higher-grade stainless steel made to endure anything nature can throw at it.

Therefore, while 304 is good for general corrosion resistance, 316 offers superior resistance. However, 316 is more brittle. Hence, fasteners like rivets and screws are often made from 304 to minimize breakage. This distinction makes sense as the bulk of the wire is exposed to the elements, whereas the fasteners are embedded in the structure.

What is the "Best" 316 Stainless Steel?

Yes, you can do better than plain old 316. There are different types/alloys of 316 stainless steel, each serving distinct purposes. Within the 316 Grade, some common types include L, F, N, H, and Ti variants. Each is slightly different, and each is designed for specific uses. We will focus on the L and the Ti versions, as both offer greatly improved corrosion resistance in non-exotic, natural world deployment scenarios.

The "L" designation indicates that 316L steel has a lower carbon content than 316. AISI 316Ti stainless is a titanium-stabilized version of Type 316 molybdenum-bearing austenitic stainless steel.

Some have claimed the superiority of 316L over 316Ti. The simple truth is that both 316L and 316Ti are excellent products. 316L has nearly the same amount of Titanium for high-temperature stability as 316Ti, but it also includes Molybdenum. This gives 316L greater corrosion resistance at lower temperatures.
