Austenite, also known as gamma-phase iron (γ-Fe), is a metallic, non-magnetic allotrope of iron or a solid solution of iron, with an alloying element.[1] In plain-carbon steel, austenite exists above the critical eutectoid temperature of 1000 K (727°C); other alloys of steel have different eutectoid temperatures. The austenite allotrope exists at room temperature in stainless steel.
