Thermal Shock Resistance Calculator
Max sudden ΔT a brittle material survives — the quench test number.
Soda-lime glass: ~60 °C (ice water in a hot tumbler — crack). Borosilicate: ~160. Fused silica: 1,000+. Low α is worth more than high strength — that's the whole Pyrex business model.
Formula
Thermal Shock Resistance Calculator is a free thermal shock for design engineers, metallurgists and QA inspectors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Thermal Shock Resistance Calculator
Max sudden ΔT a brittle material survives — the quench test number. The calculation implements ΔT_c = σ_f(1−ν)/(E·α) (Kingery — thermal stress resistance parameters). Soda-lime glass: ~60 °C (ice water in a hot tumbler — crack). Borosilicate: ~160. Fused silica: 1,000+. Low α is worth more than high strength — that's the whole Pyrex business model.

Frequently asked questions
What formula does the Thermal Shock Resistance Calculator use?+
It computes ΔT_c = σ_f(1−ν)/(E·α), per Kingery — thermal stress resistance parameters. 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?+
Soda-lime glass: ~60 °C (ice water in a hot tumbler — crack). Borosilicate: ~160. Fused silica: 1,000+. Low α is worth more than high strength — that's the whole Pyrex business model.
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 Thermal Shock Resistance 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.
