About Stainless Steel

Compare over 25 types of stainless steel to find the right material for you—all with material certificates for traceability.

Fatigue-Resistant 301 Stainless Steel

Able to withstand repeated stress and wear, 301 stainless steel has the strength required for applications such as springs and fasteners.

Springs

Corrosion-Resistant Curved Disc Springs

Made of stainless steel, these springs are more corrosion resistant than steel springs.

Constant-Force Springs

No matter how far you extend them, these springs pull back with the same amount of force.

Clip-On Constant-Force Springs

Clip the end onto a flat surface to install—no fasteners needed. Once installed, these springs pull back with the same amount of force no matter how far you extend them.

Variable-Force Springs

Unlike constant-force springs, the farther you pull these, the harder they are to pull. Use them for applications where the load becomes lighter as the spring contracts, such as in automated dispensing machines.

Rotor Springs

Wind these springs to store power, then release them to create rotary motion—similar to winding a wristwatch. Also known as clock springs and power springs.
