SSAB Boron 27
Download data sheet
SSAB Boron 27 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 27 is available in thickness range 2.00-80.00 mm and widths up to 1800 mm as coils, slit coils and CTL and 3300 mm as plate. Lengths up to 16 meters as cut to length.

Minimum bending radius of hot rolled strip products is 2 x sheet thickness. A tighter bending radius, 1 x sheet thickness, can be guaranteed for the annealed strip products.
Minimum bending radius of hot rolled SSAB Boron 27 heavy plate is 4 x plate thickness up to 16 mm thickness. For bending instructions of thicker plates, 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 plate products: are delivered with tolerances that correspond to 3/4 of EN 10029 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 plate products: width tolerance -0/+4-10 mm depending on the thickness. Length tolerance -0/+15-75 mm depending on length.
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 plate products: Shape tolerances according to EN 10029.
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 plate products: Maximum flatness deviation 6 mm/m.
Hot rolled strip products and hot rolled plate 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.
Heavy plates are as-rolled.
Hot rolled strip products are available in non-pickled, pickled dry or pickled & oiled condition.
Heavy plates are available in as rolled, shot-blasted or shot-blasted & primed condition.
