Springs · DIN 2098

A2 Stainless Steel Compression Springs

A2 Stainless Steel Compression Springs pairs the standard DIN 2098 with a A2 Stainless Steel base material. The sections below cover why engineers select this grade for compression springs, its corrosion and temperature behavior, and the sizes available.

Why Choose A2 Stainless Steel for Compression Springs

The most common stainless grade for indoor and general outdoor fasteners. For compression springs, this matters when good general corrosion resistance is the primary requirement.

Mechanical & Physical Properties

Grade designationA2-70 (304)
Magnetic responseLargely non-magnetic
Service temperatureapprox. -200 °C to +400 °C
Corrosion characteristicGood general corrosion resistance

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 A4 (316). 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.

Frequently Asked Questions

What corrosion resistance do A2 Stainless Steel Compression Springs offer?

A2 Stainless Steel Compression Springs provide good general corrosion resistance with a service range of approx. -200 °C to +400 °C.

Should I choose A2 Stainless Steel or A4 (316) for Compression Springs?

For Compression Springs, A2 Stainless Steel suits general indoor and outdoor use; A4 (316) is preferred for marine, coastal and chemical environments. Choose by corrosion exposure first.

Can A2 Stainless Steel Compression Springs gall during installation?

Yes — stainless on stainless is prone to thread galling under load, especially at smaller sizes. Use an anti-galling lubricant or wax thread compound, and slow the tightening rate where possible.

Is A2 Stainless Steel food-grade?

A2 (304) is widely accepted for food contact in non-chloride environments; A4 (316) is preferred where chlorides are present.
