A4 Stainless Steel Compression Springs

For Compression Springs in A4 Stainless Steel, the controlling decisions are corrosion, strength and service temperature. This guide summarizes those three for A4 Stainless Steel Compression Springs and lists every size we supply.

Why Choose A4 Stainless Steel for Compression Springs

Specified for marine, coastal and chemical applications. For compression springs, this matters when superior, including marine and chloride environments is the primary requirement.

Mechanical & Physical Properties

Grade designationA4-80 (316)
Magnetic responseLargely non-magnetic
Service temperatureapprox. -200 °C to +400 °C
Corrosion characteristicSuperior, including marine and chloride environments

Galvanic & Galling Considerations

Two important notes for stainless compression springs: (1) stainless can gall on stainless threads under load — use a thread lubricant or anti-galling compound, especially for M6 and below; (2) when joined to aluminum or galvanized steel, stainless can drive galvanic corrosion of the less-noble metal in wet service — isolate with a coating or sleeve where appropriate.

Comparable Grades

For Compression Springs, the alternative stainless grade is A2 (304). A2 (304) suits general indoor and outdoor service; A4 (316) adds molybdenum for marine and chloride environments. Where higher strength matters more than corrosion, switch to plated alloy-steel class 8.8 or 10.9.
