4.Heat treatment of Cr12 Steel

Isothermal annealing:

- Heat to 850°Chold for 1/2 hour to 1 hour;

- Furnace cooling to 770°C and hold at temperature for at least 10 hours;

-Cool by 10°C /h to 720°C;

-Cooling in air.

Stress relieving:

   To be carried out after machining and before the final heat treatment.

-Heat to 650-700°C, hold for 4/6 hours:

-Furnace cooling to 330-350°C;

-Cooling in air.

Hardening:

-Initial preheating to 350-450°C;

-Second preheating to 750-850°Cin salt bath at 850°C;

-Austenitizing at 960-100°C;

-Cooling in fluid oil.

Tempering hardness: 64-65 HRC

5.Application of Cr12 Steel

1.Steel with wear resistance and fairly good dimensional stability during heat treatment. 

2.Rolls for cold strip mills and wire squeezer mills, circular knives and shear blades.

3.Dies for small metal parts, punches and drawing dies, dies for sintering, forming tool rollers, shear blades.

4.Molds for plastic materials. Statically and dynamically stressed components for vehicles,engines and

 machines.

5.For parts of larger cross-sections,crankshafts,gears,wear-resisting press tool and guide palte.ect.

6.Characteristic of Cr12 Steel

1.Very high resistance against abrasive and adhesive wear due to a high volume of hard carbidesin the steel.

2.Matrix moderate machinability good dimensional stability

3.Toughness and through hardenability 

7.Machinability

The machinability rating of D3 is roughly 25 % that of free machining carbon steel 1018. 

Due to its abrasion resistant nature, machining in the hardened condition should be limited to finish grinding. 

8.Inspection
