Properties

Structural steels are carbon-manganese steels with guaranteed minimum mechanical properties (yield strength and tensile strength) and with satisfactory ductility, and are

suitable for most common applications. They are readily available from distributors in the most common forms and dimensions.

Delivery conditions proposed: AR (as rolled) or N (normalised) for thicknesses below 50 mm, normalising treatment may be replaced by a normalising rolling process.

Advantages

Structural steels offer good weldability with all conventional welding processes. In most cases pre- or post-heat treatment is not necessary. In addition to their excellent

mechanical properties, structural steels have satisfactory toughness values.

Applications

Structural steels are mainly used in the buildingindustry and in mechanical engineering. Applications include building components, containers, storage tanks and roll formedprofiles.

Recommendations for use

Options available (after prior agreement):

Chemical adjustment to improve CEV or to modify copper content Transversal impact test

Improved deformation properties perpendicular to the surface of the product as per EN 10164 (Z test) (for J2, J2+N, K2, K2+N grades)

Ultrasonic testing

Suitability for cold forming (option 11)

Structural steelsIn mechanical engineering applications, the heavy support elements are often made of structural steel.
