AusteniticAustenite
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. In plain-carbon steel, austenite exists above the critical eutectoid temperature of 1,000 K (1,340 °F; 730 °C); other alloys of steel have different eutectoid tempera…sp.infoen.wikipedia stainless steels are typically heated between 800°F (425°C) and 1700°F (925°C) to achieve an adequate stress relief. One hour at 1600°F (870°C) typically relieves about 85% of the residual stresses.Thermal Center
