DIN 1.2510 steel is defined as low alloy (containing manganese, chromium, tungsten) high carbon Oil-hardened cold work tool steel.
DIN 1.2510 steel has good toughness and impact resistance while maintaining high hardness and strength.With excellent quenching performance, DIN 1.2510 steel will still maintain excellent shape and dimensional stability at high temperatures, and its thermal fatigue resistance is especially outstanding.In addition, it also has good wear resistance.
Generally,DIN 1.2510 steel is delivered in annealed condition with hardness below 229HBW.

DIN 1.2510 STEEL FORGING
Initial Forging Temperature：1000–1100℃
Final Forging Temperature： above 850℃
Forging Ratio：above 4:1
Cooling Method After Forged:As high carbon tool steel,DIN 1.2510 steel should be annealed after forging.

DIN 1.2510 steel Annealing
There are two annealing methods for DIN 1.2510 steel. The first method is to heat the temperature to 770-790, hold it for 3-6 hours, and finally cool the furnace to 500-600℃ with the rate 30℃/h max.The second method is to heat to 780-800°C, keep warm for 2-3 hours, and then control the temperature at 670-720°C with time for 3-4 hours.Finally cooling to below 500-600°C with the rate 30℃/h max in the furnace.These two annealing methods can make the hardness of 1.2510 steel generally lower than 229HBW.
