AISI 300M Steel

Steel name: AISI 300M
Diagram No.: 6541
Type of diagram: TTA
AMS designation: 6419
AISI/SAE designation: 300M
Chemical composition in weight %: 0.40-0.46% C, 1.45-1.80% Si, 0.65-0.90% Mn, max. 0.035% P, max. 0.040% S, 0.70-0.95% Cr, 0.30-0.45% Mo, 1.65-2.00% Ni, max. 0.050% V
Steel group: Alloy steels
Note: TTA diagram for steel AISI 300M. The critical temperature Acm guarantees completion of the homogenous austenite microstructure. For conventional, slow heating Acm = 861 C. For fast induction heating the modified critical temperature Acm is distinctly bigger (for instance for vih = 1000 K/s, Acm = 1065 C). Similar tendencies are observed for the modified lower critical temperature Ac1m (beginning of austenite transformation) and the modified upper critical temperatures Ac3m (termination of austenite transformation).
