022Cr21Ni3Mo2N
022Cr21Ni3Mo2N is a grade designated under GB. Its recorded composition includes C ≤ 0.03%, Cr 19.5–22.5%, Mn ≤ 2%, Ni 3–4% and Mo 1.5–2%. No cross-standard equivalents are recorded for this grade yet. Recorded mechanical properties include Rm 655–690 N/mm², Re 450–485 N/mm² and A 25%; these figures vary with the delivery condition and dimension.

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.
Properties by condition
0 conditions · 0 values6 further values are held for this grade under a condition the source did not name — a bound with no quantity attached. They are withheld rather than shown against a guessed condition.
Heat treatment
Supply condition
- Solution annealing
Conditions the standard permits on delivery. No temperature or medium is published for these, so no order and no alternation is implied.
