Description:
DIN 1.2601/X165CrMoV12 steel is defined as cold work tool steel as per DIN 17350 standard.As a high carbon and high chromium alloy tool steel, DIN 1.2601 steel has excellent wear resistance, fatigue resistance, impact resistance, as well as good strength and toughness. It is usually delivered in the annealed condition.

The application of DIN 1.2601 steel is similar to that of DIN 1.2379 steel. it is usually used for dimensionally stable high performance cutting steel, fracture sensitive cutting dies, metal saws, press trimmers, bending dies,guillotine blades for a sheet thickness up to 6 mm, cold shearing blades, flash trimming dies, thread rolling tools, highly stressed woodworking tools, hobbing tools, extruding tools.
HEAT TREATMENT
The general annealing temperature of DIN 1.2601 steel is 850-870℃,and the holding time is 3-6 hours,and then furnace cooled to 500-600℃ with the rate 30℃/h max.Annealed hardness is usually below 255HBW.
The isothermal spheroidizing annealing temperature of DIN 1.2601 steel is 850-870 ℃, which is kept for 2-4 hours and then cooled to 720-740 ℃ with the furnace, and kept for 3-4 hours.Finally cooling to below 500-600°C with the rate 30℃/h max in the furnace and then air-cooling.Annealed hardness is usually below 255HBW.
