Gangsteel produces 430 stainless steel with consistent thermal expansion coefficient values that fully comply with the leading international standards. We can manufacture to any of the following major specifications to meet your exact project requirements:
430 stainless steel (AISI 430 / UNS S43000) is a ferritic grade with a low coefficient of thermal expansion, making it excellent for applications where dimensional stability under temperature changes is critical.
The mean coefficient of thermal expansion is as follows:
|
Temperature Range |
Mean Coefficient of Thermal Expansion (×10⁻⁶/°C) |
|---|---|
|
20 – 100 °C |
10.5 |
|
20 – 200 °C |
10.8 |
|
20 – 300 °C |
11.0 |
|
20 – 400 °C |
11.3 |
|
20 – 500 °C |
11.5 |
|
20 – 600 °C |
11.7 |
These values are typical and consistent across all major standards (ASTM A240, JIS G4305, EN 10088-2, GB/T 3280, etc.).
