80Cr20Si2Ni
80Cr20Si2Ni is a grade designated under GB. Its recorded composition includes C 0.75–0.85%, Si 1.75–2.25%, Cr 19–20.5%, Mn 0.2–0.6% and Ni 1.15–1.65%. No cross-standard equivalents are recorded for this grade yet. Recorded mechanical properties include HB 295–321; 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.
| Element | % by weight |

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 values2 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.

Conditions the standard permits on delivery. No temperature or medium is published for these, so no order and no alternation is implied.
