SAE M42 Tool Steel Material Mechanical Properties

Hardness, Rockwell C (oil quenched on 1204°C, 5 minutes): 63 HRC.

Hardness, Rockwell C (oil quenched on 1177°C, 5 minutes): 65.5 HRC

Hardness, Rockwell C(oil quenched on 1163°C), 5 minutes: 65.8 HRC


Forged of M42 Steel metal material

 

At first, Pre-Heating to 650-750℃,Then heat to forged temperature. Next, Soak at 1050-1100 °C , ensure heat thorough. Then start forged, the forged temperature no low than 950℃. After forging, cool slowly .


Heat Treatment of SAE M42 Steel

 

  • M42 HSS Steel Annealing

Firstly, Slowly heat to 870℃,then slowly Cool to 538℃(1000℉) in heat treatment furnace. Then cool in air. After annealing hardness HBS: 269 Max

  • M42 tool Steel Hardening

M42 steel having very high hardenability and should be hardened by cooling in still air. The use of a salt bath or controlled atmosphere furnace is desirable to minimize decarburization, and if not available, pack hardening in spent pitch coke is suggested. Finally, the temperature employed is usually 1800°-1850°F, depending on size section.

  • Quenching of HSS M42 Steel material

Quenching temperature / ℃ | salt bath furnace: 1177

Quenching temperature / ℃ | controlled atmosphere furnace: 11188

The heat preservation time/min: 5 ~ 15

Quenching medium: air cooling

  • Tempering Of HSS M42 Tool Steel

 

Tempering temperature / ℃ : 538

After tempering hardness HRC or higher: 66


Application of Sae M42 tool Steel HSS

 

Suitable for manufacturing various strong cutting tools with wear-resistant, resistant to impact. Advanced punching die, screw die, the toughness and complicated shape of the punch, etc. Roll cutting tool industry: scraper, serrated knife, iron knives, drill bits, etc.
