20Cr13
20Cr13 is a grade designated under GB. Its recorded composition includes C 0.16–0.25%, Si ≤ 1%, Cr 12–14%, Mn ≤ 1% and Ni ≤ 0.6%. No cross-standard equivalents are recorded for this grade yet. Recorded mechanical properties include HB 180–223; these figures vary with the delivery condition and dimension.

Chemical composition
7 elements on file · weight %What this alloy is
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
Not enough recorded composition to predict a transformation temperature for this grade — missing: Mo.
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.
