For process annealing, the steel is heated at a temperature range of _________

For process annealing, the steel is heated at a temperature range of _________ Correct Answer 550-650oC

In process annealing, the low carbon steels are heated to a temperature slightly below the A1 line, which ranges between 550oC and 650oC. Full annealing is carried out at 723-910oC (hypoeutectoid) or 723-1138oC (hypereutectoid).
