Description
S1100 steel is a structural steel with a high yield strength at a minimum of 1100 MPa.
Typical applications include demanding load-bearing structures. Despite its strength, the material is surprisingly easy to weld and bend.
S1100 steel benefits include
• Good weldability with excellent HAZ strength and toughness
• Exceptional consistency within a plate guaranteed by close tolerances
• High impact toughness which provides for good resistance to fractures
• Superior bendability and surface quality
Dimension Range
S1100 structural steel is available in plate thicknesses of 4 – 40 mm. S1100 steel is available in widths up to 3200 mm and lengths up to 14630 mm depending on thickness. More detailed information on dimensions is provided in the dimension program

Unless otherwise agreed, transverse impact testing according to EN 10025-6 option 30 will apply. For thicknesses between 6 - 11.9 mm, subsize Charpy V-specimens are used. The specified minimum value is then proportional to the cross-sectional area of the specimen compared to a full-size specimen (10 x 10 mm).

Fabrication and Other Recommendations
Welding, bending and machining
S1100 steel has obtained its mechanical properties by quenching and subsequent tempering. The properties of the delivery condition cannot be retained after exposure to temperatures in excess of 200ºC.
Appropriate health and safety precautions must be taken when welding, cutting, grinding or otherwise working on this product. Grinding, especially of primer coated plates, may produce dust with a high particle concentration.
