Heat Treatment Process
Hardening: Heat the steel evenly to 980~1020°C until the whole section reaches temperature. Then cool in air.
Annealing: Heat the steel to 870~900°C, hold it well at temperature, and then let it cool slowly inside the furnace.
Tempering: Heat the steel uniformly, hold it at the selected tempering temperature, and then allow it to cool in still air. Tempering temperature 200~540°C, hardness 61~54HRC
Application Fields
Cutting tools, stamping, woodworking, drawing, deep drawing and pressing tools, cold working rolls, measuring tools.
