Download data sheet

General Product Description

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.

Dimension Range

Toolox® 44 is available as plates in thicknesses between 6.0 - 130.0 mm. Other dimensions can be available on request.

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).

Ultrasonic testing

Ultrasonic inspection is carried out according to: EN 10160 with extra demands according to specification SSAB V6.

Tolerances

More details are given in SSAB’s brochure Toolox® Guarantees and on www.toolox.com.

Thickness

Tolerances according to Toolox® Thickness Guarantee.

Toolox® Guarantees meets the requirements of EN 10029 Class C but offers more narrow tolerances.

Length and Width
