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

          Tolerances according to EN 10029.

          Flatness

          Tolerances are according to Toolox® Flatness Guarantees, which are more restrictive than EN 10029 Class N (steel type L).

          Surface Properties

          According to EN 10163-2 Class B, Subclass 3.

          Delivery Conditions

          Quenched and Tempered at a minimum temperature of 590 °C.

          On delivery from SSAB the plates meet the following specifications:

          • Free from mill scale
          • Not repair welded

          Delivery requirements can be found in SSAB’s brochure Toolox® Guarantees or at www.toolox.com.
