Hastelloy C-276 Material Data
| Grade | UNS | Nominal chemistry focus | Typical tensile strength | Typical yield strength | Elastic modulus |
|---|---|---|---|---|---|
| Hastelloy C-276 | N10276 | Ni base, Mo 15-17%, Cr 14.5-16.5%, W 3-4.5% | 690-790 MPa | 283-355 MPa | about 205 GPa |
Typical annealed material values. Spring behavior depends on cold work, heat treatment, geometry and working stress.
C-276 Severe-Corrosion Use Cases
| Service condition | Why C-276 helps | Design check |
|---|---|---|
| Chloride-bearing process media | Strong resistance to pitting and crevice corrosion | Confirm stress corrosion risk and allowable preload loss |
| Acid and mixed chemical exposure | Broad resistance across reducing and oxidizing media | Confirm exact media concentration and operating temperature |
| Pollution control and scrubber systems | Useful in harsh wet chemical environments | Review surface finish, inspection and maintenance interval |
Hastelloy C-276 spring RFQ notes
Custom Alloy C276 spring, Hastelloy C276 spring, Hastelloy C276 disc spring manufacturer and C-276 Belleville washer supplier requests usually come from chemical, chloride or scrubber environments where common stainless grades cannot provide enough corrosion margin.
For quotation, share media chemistry, concentration, operating temperature, target load, working deflection, expected cycle duty, surface finish requirement and whether the spring is used in a flange, valve or process equipment assembly.
If the main risk is corrosion rather than very high strength, Hastelloy C-276 may be a better review path than defaulting to Inconel 718.
Requests involving washer Hastelloy C276, Alloy C276 Belleville washer supplier and custom Alloy C276 springs are best answered with corrosion media, load target and quantity together, because material choice and spring geometry should be reviewed at the same time.
For buyers comparing Hastelloy springs with Inconel 625 or Alloy 718, FeTech can first decide whether corrosion, high strength, temperature or long-term load retention is the real driver, then quote the custom spring geometry.

Common Product Questions
Why choose Hastelloy C-276 instead of stainless steel?
C-276 is considered when chloride, acid or mixed chemical environments exceed the confidence range of common stainless and precipitation-hardening stainless grades.
Is Hastelloy C-276 mainly a high-temperature spring alloy?
Its main reason for selection is corrosion resistance. For very high-temperature load retention, Inconel or Nimonic grades may be a better first review.
What should a custom Alloy C276 spring RFQ include?
Share the chemical media, concentration, normal and peak temperature, target load, working deflection, available stack space, drawing, quantity and inspection needs. For custom Alloy C276 spring or Hastelloy C276 disc spring supplier RFQs, media and load data are more useful than material name alone.
