Common Types of Spring Steel
Spring steel can be classified based on composition and use:
1. Carbon Spring Steel
-
High carbon content (~0.5–1.0%)
-
Very strong and hard
-
Examples: 1075, 1095 steel (U.S. designation)
-
Common for leaf springs, coil springs
2. Alloy Spring Steel
-
Contains elements like chromium, vanadium, or silicon
-
Better wear resistance, toughness, and fatigue life
-
Examples: SUP7, 65Si7, 51CrV4
3. Stainless Spring Steel
-
Corrosion-resistant
-
Good for harsh environments
-
Examples: AISI 302, 316 stainless spring steel
4. Tool Steel (sometimes used as spring steel)
-
High hardness and strength
-
Used in small, high-performance springs
🧰 Common Forms
-
Flat strips / sheets – for leaf springs, clips
-
Round wire – for coil and torsion springs
-
Bars – for custom-machined spring components
