For the high corrosivity condition, the Cr content in the austenite must be well above 12%. To obtain this, a second calculation was made increasing the Cr content of the alloy to 31% and decreasing de C content to 2.2%. As shown in Fig. 4 this would result in a mixture of ferrite and low C austenite at the temperatures used for heat treatment ...
