Product Description


The high-strength structural steel at 1100 MPa

S1100MC steel is a hot-rolled structural steel made for cold forming, with a minimum yield strength of 1100 MPa for stronger and lighter structures.


These cut-to-length sheets feature excellent thickness accuracy and surface quality in relation to strength level, providing an outstanding finish to the final products.


Typical applications include a wide range of parts and components such as demanding load-bearing structures.


Dimension Range

S1100MC steel is available as cut to length sheets in thicknesses of 3.00 to 8.00 mm, widths up to 1700mm and lengths up to 16 meters.

Delivery Conditions

Thermomechanically Rolled. S1100MC steel is available in as rolled surface condition.

Fabrication and Other Recommendations


S1100MC steel has good welding, cold forming and cutting performance.

S1100MC steel is not suited for applications requiring hot working or heat treatments at temperatures above 200°C since the material then may lose its guaranteed properties.
