Stainless Steel Materials Used in Spring Manufacturing

There are four common grades of stainless steel used in spring manufacturing. Depending on the application, a Lee Spring engineer can assist you in selecting the correct material for your application. Some areas to consider when selecting the right material are corrosive properties that interact with the spring and temperature in and around the application.

Stainless Steel 302
General purpose corrosion and heat resistant spring wire. Slightly magnetic.
ASTM A313
Maximum Operating Temperature: 550° F (288° C)

Stainless Steel 304
General purpose corrosion and heat resistant spring wire. Slightly magnetic. Type 304 has less carbon than Type 302, however considered commercially equivalent for stock springs.
ASTM A313
Maximum Operating Temperature: 550° F (288° C)

Stainless Steel 316
General heat resistant spring wire and better corrosion resistance than Type 302/204. Slightly magnetic. Often used in marine applications, resists chloride attack.
ASTM A313
Maximum Operating Temperature: 550° F (288° C)

Stainless Steel 17-7 PH
Improved strength over 300 Series stainless steels with similar heat and corrosion resistance. Slightly magnetic. Material is precipitation hardened after spring fabrication to achieve desired properties.
AMS 5678
Maximum Operating Temperature: 650° F (343° C)
