What type of stainless steel is used in springs?

Grade 302 stainless is a general purpose stainless which is typically made up of 18% Chromium and 8% Nickel. 302 is the most commonly used stainless wire for springs due to the high corrosion resistance and good tensile properties it offers.

What is 316L wire?

Alloy 316 is a general purpose austenitic stainless steel with a face centered cubic structure. It is essentially non-magnetic in the annealed condition and can only be hardened by cold working. The lower carbon content of alloy 316L gives even better corrosion resistance in welded structures.

What are the properties of spring steel?

Unique Properties of Spring Steel Spring steel is known to be resilient and pliable with a high yield strength. It has the unique ability to be formed, shaped, and post heat treated. These physical characteristics are what allow spring steel to be a general use steel.

What are the properties of stainless steel spring wire?

Several new compositions are now available to withstand corrosion. All of these materials can be used for high temperatures up to 650°F. Cold drawn. Heat resistant and better corrosion resistance than 302. Magnetic in spring temper.

Which is better stainless steel spring wire or 302?

Type 316’s tensile strength is 10-15% lower than that of Type 302, and the alloy is slightly less magnetic in the spring temper than Type 302. Similar in composition to Type 302, Type 316 stainless steel wire has a slightly higher nickel content and 2-2.50% molybdenum giving this alloy better corrosion resistance.

What makes 316 stainless steel wire so strong?

Alloy 316 is an austenitic chromium-nickel stainless steel containing molybdenum. This addition increases corrosion resistance, improves resistance to pitting chloride ion solutions and provide increased strength at elevated temperatures.

What are the grades of stainless steel springs?

The wire sizes of 316 stainless steel springs vary from 0.006″ to 0.072″. Grade 302: These springs are resistant under temperatures as high as 550 oF (228 oC). This grade comprises chromium, nickel, manganese, carbon, and silicon.
