Materials Options for Wave Springs

Standard Materials

SAE 1070-1090 Carbon Steel (ST)

This pre-hardened material is the standard material for wave springs. It is the less expensive option to Stainless Steel.

17-7 Stainless Steel (SQ)

This is used for high stress and fatigue applications. It has higher corrosion resistance than SAE 1070-1090, and can withstand much higher temperatures without loosing spring qualities.

Special Material Grades

AISI 302 Stainless Steel (SJ)

This general purpose stainless steel offers corrosion resistance and can be cold worked to high tensile strengths.

AISI 316 Stainless Steel (SU)

This type of stainless steel is heat resistant with superior corrosion resistance than other chromium nickel steels. It offers high creep strength at elevated temperatures and resistance to pitting.

Elgiloy (EG)

High-performance alloy known for its exceptional resistance to corrosion, high-strength and excellent mechanical properties.

Beryllium Copper (BC)

Applications that require conductivity are best served by this material. It is also characterized by excellent corrosion resistance and is particularly effective in sea, air and seawater atmospheres.


A286 Stainless Steel (SY)

This grade of stainless steel is a nickel based alloy that exhibits strength, oxidation resistance and can operate in temperatures up to 1000°F.

Inconel X-750 (IC)

This nickel-cobalt alloy has excellent resistance to corrosion and oxidation. It can be heat treated in a particular way to withstand temperatures to 1200°F.

Hastelloy C276 (HE)

High performance alloy is known for its exceptional corrosion resistance in aggressive environments. Excellent pitting resistance and typically used in industries such as chemical processing, oil & gas and aerospace.

Phosphor Bronze (PB)

This type exhibits higher strength compared to standard phosphor bronze materials with the same tin percentages. It is also characterized by very good stress relaxation characteristics. (Note: Rotor Clip can also supply phosphor bronze material to DIN standard 17 662, Material Number 2.1020. Contact Rotor Clip Technical Sales for more information).

Oil Dip (OIL)

This standard finish for carbon steel spiral retaining rings offers an extended shelf-life protection against rusting. RoHS & ELV compliant.

Black Oxide (BO)

This flat, black finish is used more for when aesthetics of the part are a factor with minimal corrosion protection. RoHS & ELV compliant.


This process removes a thin layer of material from the part resulting in a shiny finish with improved corrosion resistance.


The passivation process removes “free iron” contamination left behind on the surface of stainless steel due to the manufacturing process. Also, the passivation process facilitates the formation of a thin, transparent oxide film that protects the stainless steel from selective oxidation (corrosion).
