Carburizing Case Depth Calculator
Effective case depth from time and temperature (Harris equation).
Diffusion's square-root tax: doubling case depth takes 4× the furnace time. At 925 °C expect ~0.6 mm in 4 h. Gears spec case depth ≈ 0.15–0.2 × module.

About Carburizing Case Depth Calculator
Effective case depth from time and temperature (Harris equation). The calculation implements d = K·√t, K = 660·e^(−8287/T) (Harris) (Harris (1943); ASM Heat Treating handbook). Diffusion's square-root tax: doubling case depth takes 4× the furnace time. At 925 °C expect ~0.6 mm in 4 h. Gears spec case depth ≈ 0.15–0.2 × module.

Frequently asked questions
What formula does the Carburizing Case Depth Calculator use?+
It computes d = K·√t, K = 660·e^(−8287/T) (Harris), per Harris (1943); ASM Heat Treating handbook. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
Diffusion's square-root tax: doubling case depth takes 4× the furnace time. At 925 °C expect ~0.6 mm in 4 h. Gears spec case depth ≈ 0.15–0.2 × module.
Where do the material property defaults come from?+
Defaults are standard handbook values (ASM, manufacturer datasheets, the cited standard). Always substitute certified values from your material's test certificate for critical work.
Is the Carburizing Case Depth Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
