Steel name: AISI 304
Diagram No.: 3809
Type of diagram: TTP
AISI designation: 304
Chemical composition in weight %: 18.7% Cr, 9.0% Ni, 1.73% Mn, 0.6% Si, 0.05% C.
Note: TTP (Time Temperature Precipitation) diagram for the formation of Sigma in an AISI 304 steel of
composition: 18.7Cr, 9.0Ni, 1.73Mn, 0.6Si, 0.05C wt%. Predictions (right), with indication of the
temperature in , are compared to the TTP diagram obtained by Minami [2] (left). The nose of the TTP
curve is in both cases obtained at 750
oC.
