Pre-hardened, precise, predictable steel.
Toolox® 44 is a steel already heat treated to the final properties.Thus saving time, costs and risks associated with heat treatment.
The very high strength is combined with a high and guaranteed toughness as well as an excellent fatigue resistence. Making Toolox® 44 the ideal choice for the most demanding engineering and mould and die applications.
Toolox® 44 can be surface hardened with methods like nitriding, laser and induction. Giving the possibilities to even further improve the performance.
Toolox® 44 is available as plates in thicknesses between 7.874" - 5.118", as forged block in thicknesses between 5.906" - 12.598", and as round bars in diameters between 0.827" - 13.898". Other dimensions can be available on request. For more information concerning dimensions and tolerances, see Toolox® round bars or Toolox engineering & tool steel dimensional program
1) Hardness is measured, according to EN ISO 6506-1. The measurement is performed on a milled surface 0.492" below the ordered surface for forged blocks and round bars. Bar hardness is measured with indents positioned as impact test according to EN 10083. For plate the measurment is preformed on a milled surface 0.020" - 0.079" below the surface.
1) Impact testing according to EN 10 025, EN ISO 148 with a 0.079" striker.
2) Impact testing according to EN 10083.
