Properties of Stainless Steel Springs

The three most common stainless steel springs are AISI 302/304, AISI 316, and 17-7 (AISI 631). Each of these types of springs have unique properties and are used for different applications. Whether it’s a stainless steel compression, coil, or extension spring, choosing the right type of spring will ensure optimal performance for your intended use.

AISI 302/304 Stainless Steel Wire Springs

As one of the most popular stainless steel spring types, these are known for their strength and performance in harsh environments. These springs feature high corrosion resistance, good tensile strength, heat resistance (up to 550° F), and slight magnetic properties. Some common applications that use AISI 302/304 stainless steel wire springs include the medical industry, food processing, and the dairy industry. 

AISI 316 Stainless Steel Wire Springs

These steel wire springs have some of the best cold forming properties and offer short-term creep and tensile strength at temperatures up to 550° F. These springs have superior corrosion resistance over 302/304 stainless steel wire but have less tensile strength. AISI 316 stainless steel wire springs are often used by industries such as oil and gas, marine, refinery, pharmaceutical, and more.

17-7 PH (AISI 631) Stainless Steel Springs

These stainless steel springs are commonly used in all types of spring applications because of their longevity in extreme environments. At up to 650° F, these springs feature great fatigue properties, high yield strength, ductility, excellent strength-to-weight ratio, elasticity, and good corrosion resistance. 17-7 (AISI 631) stainless steel springs are ideal for use in petrochemical and chemical processing, the energy industry, and automotive applications. 

Benefits of Using Stainless Steel Springs

Stainless steel springs offer a multitude of benefits, making them preferred over other types of springs. These benefits include:

  • Improved resistance to corrosion
  • Resistance to high temperatures
  • Better structural integrity
  • Ideal for extreme temperature and moist environments
  • Easy to clean
  • Aesthetic appeal
  • Great product purity
