Thermal Expansion Coefficients: stainless_304
Coefficient of linear thermal expansion (CTE, alpha) as a function of temperature for common engineering materials — steels, stainless steels, aluminum alloys, titanium, nickel superalloys, copper alloys, ceramics, and polymers at temperatures from -200C to 2000C (material-dependent)
| material | temperature C | CTE 1e6 per C (1e-6/C) | material category | mean CTE from 20C 1e6 per C (1e-6/C) | notes |
|---|---|---|---|---|---|
| stainless_304 | -200 | 12 | steel | 13.5 | Austenitic SS; remains stable at cryogenic due to FCC structure |
| stainless_304 | -100 | 14.8 | steel | 15.4 | Austenitic SS 304 |
| stainless_304 | 0 | 16.2 | steel | 16.8 | Austenitic SS 304 |
