A certain component is to be carburized to obtain 0.592 wt % C at a depth of 2.0 mm.
After carburizing (for 1.2 hours) the heat treater finds that he achieved 04 wt % C at
a depth of 2.0 mm. His furnace only operates at a 900 C and maintains a constant
atmosphere of 1 wt % C The steel used has an initial carbon content of 0.2 wt %.
How long (in hours) should he carburize to achieve his goal?
