We have added more technical details for structural steel grades! Check out our newest steel grade pages that include mechanical and chemical property details.
S355 structural steel gradesMore
S355 structural steel grades are mainly used in building and civil engineering applications.
These structural steel grades are carbon-manganese steels with guaranteed minimum mechanical properties (yield strength and tensile strength) and with satisfactory ductility. They offer good weldability with all conventional welding processes. In addition to their excellent mechanical properties, structural steels have satisfactory toughness values, especially with +N or +M.
S420 & S460 high strength structural steel gradesMore
S420 and S460 high strength structural steel grades are weldable, fine grain structural steels that offer good weldability with all conventional welding processes.
These steels are used for welded parts that must withstand high levels of strain. Typical applications are bridges, long span structures, high-rise buildings, and other architectural structures.
Each grade can be obtained with guaranteed impact properties at -20°C (N or M grades), or for low-temperature applications, at -50°C (NL or ML grades).
