Steel name: SAE 4047
  Diagram No.: 2876
  Type of diagram: TTE
  SAE: 4047
  Chemical composition in weight %: 0.48% C, 0.83% Mn, 0.28% Si, 0.019% P, 0.015% S,
  0.14% Ni, 0.13% Cr, 0.25% Mo.
  Note: Embrittlement diagram. Temper embrittlement. Austenitizing temperature: 815 ^oC
  (1500 ^oF). Grain size: 7. Figures beside points represent increase in transition
  temperature (^oF) based on transition temperatures of specimens tempered at 1260 ^oF
  for 5 s. Figures in parentheses are the average hardness of the speicmens in that series.
