SSAB Boron 33Cr
Download data sheet
SSAB Boron 33Cr is steel for quench- and press hardening. The degree of hardness and toughness that can be achieved after heat-treatment will provide the final products with wear- and shock resistance properties that assure longer lifetime.
SSAB Boron 33Cr is available in thickness range 2.00-16.00 mm and widths up to 1800 mm as coils, slit coils and CTL. Lengths up to 16 meters as cut to length.

Minimum bending radius of hot rolled SSAB Boron 33Cr strip products is 2 x sheet thickness. A tighter bending radius, 1 x sheet thickness, can be guaranteed for the annealed strip products. For further information, please contact SSAB’s Tech Support.
A test certificate according to EN 10204/2.2 (chemical composition) is part of the delivery.
A test certificate according to EN 10204/3.1 can be provided by special agreement only.

SSAB Boron steels are delivered with SSAB Boron tolerances which meet and exceed the requirements in corresponding EN standards. Tighter tolerances are available on request.
Hot rolled coils and sheet products: according to SSAB Boron thickness tolerances that exceed EN 10051 and correspond to 2/3 of EN 10051 as default value.
Hot rolled coils and sheets with mill edges: SSAB Boron width tolerances are corresponding to -0/+20 mm.
Hot rolled coils and sheets with cut edges: SSAB Boron width tolerances are corresponding to -0/+2 mm.
Hot rolled coils and sheets: SSAB Boron is delivered with shape tolerances according to EN 10051. Tighter shape tolerances are available on request.
Hot rolled sheets: SSAB Boron tolerances guarantee a maximum flatness deviation of 6 mm/m in addition to the EN 10051 flatness requirements. Flatness guarantees only apply for cut to length sheets.
Hot rolled strip products: According to EN 10163-2 Class A, Subclass 3.
Hot rolled coils and sheets are delivered in as-rolled or by separate agreement annealed condition.
Hot rolled strip products are available in non-pickled, pickled dry or pickled & oiled condition.
