Heat Treatment of ESR M35 / 1.3243 High Speed Tool Steel:

1. Annealing

   • Hardness (HB): 269
     Annealing softens the steel to reduce internal stresses and improve machinability.

2. Hardening

   • Temperature: 1200-1220°C
     The steel is heated to this temperature range to increase hardness and strength.

3. Tempering

   • Temperature: 550°C
     Tempering at 550°C helps to reduce brittleness while maintaining strength and wear resistance.

4. Tempered Hardness (HRC): 64-67
   After tempering, the hardness of the steel is in the range of 64-67 HRC, offering a good balance of toughness and hardness for machining tasks.

Process	Temperature	Hardness	Description
Annealing	-	269 HB	Softens steel and reduces stress.
Hardening	1200-1220°C	-	Increases hardness and strength.
Tempering	550°C	64-67 HRC	Reduces brittleness, balances hardness.
