Engineering Materials In process annealing, the hypo eutectoid steel is Heated below or closes to the lower critical temperature and then cooled slowly Heated from 30°C to 50°C above the upper critical temperature and then cooled in still air Heated from 30°C to 50°C above the upper critical temperature and then cooled slowly in the furnace Heated from 30°C to 50°C above the upper critical temperature and then cooled suddenly in a suitable cooling medium Heated below or closes to the lower critical temperature and then cooled slowly Heated from 30°C to 50°C above the upper critical temperature and then cooled in still air Heated from 30°C to 50°C above the upper critical temperature and then cooled slowly in the furnace Heated from 30°C to 50°C above the upper critical temperature and then cooled suddenly in a suitable cooling medium ANSWER DOWNLOAD EXAMIANS APP
