Question:
Find a time-temperature-transformation (TTT) diagram for 1340 steel. Assume that the steel is held at 1330 °F for 1 h, quenched to 800 °F and held for 1000 s at this temperature, and then cooled in air to room temperature.
(a) What is the microstructure and hardness of the steel after the heat treatment?
(b) What are the designation, hardenability, and applications of this steel?
(c) What are the mechanical properties of this steel delivered as hot rolled, normalized, and annealed when empered at 800 °F and oil-quenched?
