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

Answer 1

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)?

Answer 2

The coefficient of thermal expansion for HY-100 carbon steel is approximately 6.5 to 7.5 × 10^-6 per degree Celsius (°C). This value can vary slightly based on the specific composition and treatment of the steel. It's important to refer to material specifications or datasheets for precise values in engineering applications.
