Consult the carbon content of austenite
Pure iron carbon alloys, austenitic (A) carbon content in different grades, different temperature and different, in more than 727 degrees (727 degrees when the carbon content is 0.77%), 1148 degrees, 2.11% carbon content with see iron carbon phase diagram
It only refers to the iron carbon two element alloy, and the other alloys are different.
