STAINLESS STEEL SPRING WIRE

There are four types of stainless-steel wire that are commonly used in the spring industry. Generally speaking, all stainless-steel wire contains 70% iron and 30% Chromium, Nickel and other alloying elements.

-Stainless 302/304—This type of stainless is often called “18/8” stainless, which refers to its 18% Chromium and 8% Nickel content. This series of stainless is tough, ductile, and exhibits good corrosion resistance. Type 304 stainless has a slightly lower carbon content than 302, which results is better corrosion resistance but a lower tensile strength. In many cases, this will allow 302 to be substituted for 304 in applications where the added corrosion resistance is not required.

-Stainless 316—This material, because of its higher molybdenum and nickel content, is more resistant to corrosion than 302/304. Conversely, type 316 has a lower tensile strength than 302/304.

-Stainless 17-7— 17% Chromium and 7% Nickel. This material also contains a very important addition of 1% aluminum. Stainless 17-7 can withstand surface temperatures up to 180-200°F higher than Types 302/304. It also has a significantly higher tensile strength than 302/304/316.
