Type 302/304 Stainless Steel: Springs are manufactured to meet ASTM-A313, a high quality wire. For temperatures up to 550°F. Slightly magnetic. It is the most 

At one time coil springs for automotive suspensions were 5160 or 9260, now some of them are a high-alloy low carbon precipitation-hardening 

Stainless steel is the most popular alloy for springs. They have a high degree of resistance to heat and to corrosion, which means they're useful for 

They are typically made of a single strand of metal that follows a helical path, resulting in a coil. Coil springs are made by wrapping the strand of metal around a cylinder. While all coil springs share this helical design, some of them have unique features that distinguish them from the rest.

Since blue tempered steel springs work well with heat treatment, the next step for this type of steel spring is to be annealed, or made softer through heating, 

Stainless Steel is quite a popular material for metal coil springs. There are three main types of stainless steel wire: Stainless Steel 302 (ASTM A-313), 

Steel alloys are the most commonly used spring materials. The most popular alloys include high-carbon (such as the music wire used for guitar strings), oil- 

Spring steel is used in the manufacture of springs for automotive and industrial suspension, generally using low-alloy manganese, medium/high-carbon steel 

9Mn-1.0Si steel containing 0.45 to 0.65 percent chromium has been used for coil springs in several models of General Motors cars since 1977.

The material used to made springs are called a spring steel. Spring steels are mostly low-alloy manganese, low carbon steel or high carbon steel with very high yield strength. Examples of spring materials are as follows: 1. Oil Tempered Steel 2. Stainless Steel 3. Elgiloy 4. Carbon Value 5. Iconel 7. Monel 6. Titanium 7. Chrome Silicon

May 21,  · Stainless steel: Stainless steel is the third most common type of wire for metal springs, primarily favored for its resistance to corrosion. Stainless steel comes in many varieties, all with different levels of elasticity and hardness. Stainless steel springs are often found in devices used for medical purposes or outdoor applications.
