General Product Description
SSAB Domex 355MC Plus is a HSLA steel with enhanced toughness and local formability properties. The new generation HSLA steels are produced with carefully controlled production parameters resulting in a finer microstructure and low variation in the mechanical properties. Fine microstructure will significantly improve the cut edge quality, lead to improved local formability while still retaining an excellent global formability and improve the toughness.
Dimension Range
SSAB Domex 355MC Plus is available in thicknesses of 3.00-12.00 mm and widths up to 1860 mm as coils, slit coils and as cut to length in lengths up to 16 meters.

Tolerances
SSAB Domex is delivered with SSAB Domex tolerances, with improved guarantees compared to EN 10051. More details are available at SSAB.com
Thickness
SSAB Domex thickness tolerances correspond to 2/3 of EN 10051 as default value. After special agreement, tolerances down to 1/3 of EN 10051 can be delivered for certain products and dimensions.
Length and Width
SSAB Domex tolerances for width and length are according to SSAB standard and offer narrower width and length tolerances compared to EN 10051.
For coil and sheet with mill edge, the width tolerances are corresponding to -0/+20 mm.
For coil and sheet with cut edge, the width tolerances are corresponding to -0/+2 mm.
After special agreement, tighter tolerances can be delivered for certain products and dimensions. Length tolerances only apply for cut to length sheets.
Shape
According to EN 10051. Narrower tolerances are available on request.
Flatness
SSAB Domex tolerances guarantee a maximum flatness deviation of 3 mm/m in addition to the EN 10051 flatness requirements.
Flatness guarantees only apply for cut to length sheets.
Surface Properties
According to EN 10163-2 Class B, Subclass 3.
Delivery Conditions
Thermomechanically rolled.

Fabrication and Other Recommendations
SSAB Domex MC are cold forming steels not suited for heat treatments at temperatures above 580°C, since the material may then lose its guaranteed properties.
SSAB Domex is well suited for all common thermal and mechanical cutting processes. SSAB Domex offers good cold forming properties. Welding can be performed, using all common methods and consumables.
For information concerning fabrication, see SSAB´s brochures on www.ssab.com or consult Tech Support.
Appropriate health and safety precautions must be taken when bending, welding, cutting, grinding or otherwise working on the products.
