What this alloy is

Iron — the balance, never listed by a standard — 96.5 %Cr — 1.1 %Mn — 0.9 %C — 0.5 %Traces & impurities · 1 %

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 values

4 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

Stress relieving
Quenching and Tempering
Soft annealing

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