Steel name: C-Mn Steel
  Diagram No.: 2873
  Type of diagram: TTE
  Chemical composition in weight %: 0.26% C, 1.63% Mn, 0.28% Si, 0.021% P, 0.034% S.
  Note: Embrittlement diagram. Temper embrittlement. Treatment: Austenitized at 845^oC
  (1550^oF) for 1 h, water quenched. One set tempered at 660^oC (1225^oF) for different
  times (3 min, 15 min, 1 h, 10 h, 100 h). Another set tempered at 660^oC (1225^oF) for 1 h,
  then given additional tempers between 455 and 595^oC (850 and 1100^oF) for 1, 10 and
  100 h. See the diagram No. 2874.
