What this alloy is

Iron — the balance, never listed by a standard — 74.8 %Mn — 15.5 %Al — 2.8 %Cr — 2.3 %Traces & impurities · 4.6 %

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: Ni.

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.

Heat treatment

Supply condition

  • QuenchingTest specimen

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