022Cr12Ni9Cu2NbTi
022Cr12Ni9Cu2NbTi is a grade designated under GB. Its recorded composition includes C ≤ 0.03%, Ti 0.8–1.4%, Cr 11–12.5%, Ni 7.5–9.5% and Cu 1.5–2.5%. No cross-standard equivalents are recorded for this grade yet. Further recorded physical values: E 170–200 GPa, λ 17.2 W/(m·K), α 10.6–12 ·10⁻⁶/K, cp 460 J/(kg·K) and ρ el. 900 nΩ·m; several of these are temperature-dependent.

Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade.

The scale is logarithmic, not the element’s raw share of the alloy — the only honest way to fit 0.01 % and 100 % in one picture, and it means every value here can be compared with every other.

The published column is the source string byte-for-byte, decimal comma and all; Min and Max are the parsed bounds. Elements not listed have no value on file — they are omitted, never inferred.
Predicted transformation temperatures
This grade's composition falls outside the published model's validated range (a low-alloy composition window), so no transformation temperature is predicted here.
Physical & mechanical properties
An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook. It does not mean the property is undefined for the material.

Every figure holds only for the condition on its own row. Values are never merged across conditions or across sources, never averaged, and never interpolated between two rows. An em dash means no value on file — never zero. Figures are converted to the unit in the column header; the source’s own wording is kept and shown where the two differ.
