AISI 304, 316 and X6CrNiMoTi17-12-2 Steels

Steel name: AISI 304, 316 and X6CrNiMoTi17-12-2
Diagram No.: 3782
Type of diagram: TTS
AISI/SAE designation: 304, 316
DIN designation: X6CrNiMoTi17-12-2
Chemical composition in weight %:
AISI 316: 0.05% C, 0.47% Si, 0.86% Mn, 0.028% P, 0.001% S, 17.55% Cr, 2.10% Mo, 11.56% Ni, 0.017% N
AISI 304: 0.04% C, 0.54% Si, 1.08% Mn, 0.032% P, 0.008% S, 18.52% Cr, 0.21% Mo, 8.47% Ni, 0.012% N
X6CrNiMoTi17-12-2: 0.021% C, 0.45% Si, 1.51% Mn, 0.030% P, 0.001% S, 17.60% Cr, 2.01% Mo, 10.73% Ni, 0.015% N
Steel group: Stainless steels
Note: From the TTS diagram it can be seen that the nose of the C-curve corresponding to the maximum rate of sensitisation occurs at 800°C for AISI 316, the TTS diagram for AISI 304 is shifted towards lesser time. The sensitisation of the stabilised austenitic stainless steel X6CrNiMoTi 17-12-2 begins at the temperature 750°C and t (min) ~ 80 h.
