What is the coefficient of thermal expansion for HY-100 carbon steel?

That’s a clear and technically accurate summary of the coefficient of thermal expansion (CTE) for HY-100 carbon steel.

Here’s a slightly refined version with improved precision and academic tone, suitable for reports or technical writing:

Revised version:

The coefficient of thermal expansion (CTE) for HY-100 carbon steel typically ranges from 6.5 × 10⁻⁶ to 7.5 × 10⁻⁶ per degree Celsius (°C). The exact value can vary depending on factors such as the *steel’s composition, heat treatment, and microstructure*. For engineering and design applications requiring high accuracy, it is essential to consult official material specifications or manufacturer datasheets to obtain precise values.

Would you like me to include a brief explanation of how this property affects engineering design (for example, in welding, pressure vessels, or naval applications)?
