They are available in very high strength steels including ASTM A913/grades 485, 450 and 345 MPa (70, 65 and 50 ksi), ETA-10/0156/HISTAR 460, EN 10025 4 S460M and in normal strength steel grades (355 MPa).
An outstanding feature of these very high strengh steels is their low carbon equivalent values, allowing easier processing by the fabricators. As such, preheating before welding can ususally be avoided and lead to substantial time and cost savings.
When the design of an element is not governed by deflection, higher strengh steel enables an average of 20% weight and cost reduction of the structural elements.
