2-1/4Cr-1% Mo Steel
Steel name: 2-1/4Cr-1% Mo Steel
Diagram No.: 2826
Type of diagram: TTP
Chemical composition in weight %: 0.15% C, 0.18% Si, 0.50% Mn, 0.018% P, 0.012% S, 2.12% Cr, 0.94% Mo, 0.165% Ni, 0.077% Cu, 0.009% Sn
Steel group: Alloy steels
Note: Precipitation diagram. Precipitation during aging (tempering).
Austenitizing temperature: 960oC (1760oF) for 2 h. Diagram showing the sequence of carbide formation on tempering the quenched steel. Treatmnet: After austenitizing, half the specimens were cooled at 300oC (570oF) per hour to room temperature, and the remainder were quenched in oil. Tempering treatments were carried out in a lead bath at 400, 500 and 600oC (740, 930 and 1110oF) and in an electric air furnace at 650, 700 and 750oC (1220, 1290 and 1380oF).
See the diagram No. 2825 and No. 2824.
