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.
1) Hardness is measured, according to EN ISO 6506-1, on a milled surface 0.5 - 2 mm below the plate surface.
1) Unless otherwise agreed, transverse impact testing according to EN 10025-6 option 30 will apply. For thicknesses between 6 - 11.9 mm, sub-size Charpy V-specimens are used. The specified minimum value is then proportrional to the cross-sectional area of the specimen compared to a full-size specimen (10 x 10 mm).
Tolerances according to Toolox® Thickness Guarantee.
Toolox® Guarantees meets the requirements of EN 10029 Class C, but offers more narrow tolerances for plates.
Thickness tolerances for Toolox® forged blocks are according to 0/+3.2 mm.
Length and width tolerances according to EN 10029 for Toolox® plates.
Length tolerances for Toolox® forged blocks are -500/+500 mm.
Tolerances for Toolox® plates are according to Toolox® Flatness Guarantees, which are more restrictive than EN 10029 Class N (steel type L).
Maximum accepted flatness deviation for Toolox® forged blocks are 1 mm/m.
According to EN 10163-2 Class B, Subclass 3 for Toolox® plate.
Surface condition for Toolox® forged blocks are milled to roughness of max Ra 12.5 um, and oiled as corrosion protection.
Quenched and Tempered at a minimum temperature of 590 °C.
