Product Description
Double-groove Disc Spring Material Guide: Technical Specifications, Application Scenarios & Surface Treatment Pairings
Material selection is a critical determinant of performance for double-groove disc springs—specialized elastic components featuring precision-machined radial grooves on both inner and outer circumferential surfaces. Our comprehensive material portfolio is engineered to address diverse operating conditions, with each alloy formulation optimized for specific environmental and mechanical demands.
Material Specifications & Applications
65Mn Carbon Steel
Exceptional elasticity (elastic modulus ≈206 GPa) and cost-effectiveness
Ideal for medium-load scenarios such as packaging machinery and printing equipment
SUS304/SUS316 Austenitic Stainless Steel
Superior corrosion resistance with SUS304 providing ≥500 hours salt spray resistance and SUS316 extending durability in marine/offshore applications with pH 2-12 acid-alkaline tolerance
Excel in humid/chemical environments
50CrVA/60Si2MnA Alloy Steel
High stiffness (yield strength ≥1200 MPa for 50CrVA) and fatigue resistance exceeding 1 million cycles
Critical for hydraulic systems and automotive powertrain components
Inconel718/Inconel X-750 Nickel-based Superalloys
Maintain structural integrity from -270℃ to 700℃ (Inconel718 retains 85% of room-temperature strength at 650℃)
Dominate high-temperature aerospace applications for gas turbine and spacecraft engine components
Surface Treatment Pairings
Each material undergoes tailored surface treatments to synergistically maximize service life and performance under targeted operating conditions:
| Material | Surface Treatment | Performance Benefits |
|---|---|---|
| 65Mn Carbon Steel | Phosphating or Black Oxide Coating | 40% corrosion resistance improvement |
| SUS304 Stainless Steel | Passivation | Enhanced oxide film stability |
| 50CrVA Alloy Steel | Mechanical Galvanizing | 25% wear resistance boost |
| Inconel718 | Dacromet Coating | Extreme temperature oxidation protection |
