6. Heat Treatment
Annealing : Slowly heat to 760 – 810 ℃， then slowly Cool to 500 ℃ in heat treatment furnace. Then frosty in make public. After annealing hardness HBS: 235 Max
Hot working temperature / ℃ ： 1050
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
