General Product Description

The pre-hardened, exceptionally clean tool and engineering steel.

Thanks to its low carbon and alloy content, Toolox® 33 is perfectly adaptable for welding as well as hot cutting. Giving the possibility to product components more cost efficient by saving machining time.

Delivered in quenched and tempered condition, Toolox 33 features high impact toughness and very low residual stresses to achieve good dimensional stability after machining. Toolox® 33 is suitable for mold and dies as well as tooling and engineering components. By using the proper surface engineering methods, you can significantly extend the service life of your tools and components.

Dimension Range

Toolox® 33 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
