Steel name: 3.25% Si Steel
  Diagram No.: 2792
  Type of diagram: TTT
  Chemical composition in weight %: 0.051% C, 0.21% Mn, 3.44% Si, 0.010% P, 0.011% S.
  Note: Precipitation diagram. Silicon steel. Austenitizing temperature: 1095^oC (2000^oF).
  Treatment: Before transformation, specimens were heated to 1095^oC (2000^oF) at which
  temperature the 0.05% C steel contained approximate 20% and the 0.033% C steel
  approximate 7% austenite. Transformation of this austenite was investigated at
  temperatures from 815 to 540^oC (1500 to 1000^oF). Specimens were plated with nickel,
  then heated for 15 min at 1045^oC (2000^oF) in a continuously evacuated silica tube. At
  the end of this period the vacuum was broken and the specimens quickly transfered to
  a lead bath at the desired transformation temperature. See the diagram No. 2793.
