Steel beam HISTAR®

Iframing

HISTAR® steels are innovative structural steel grades with a low alloy content available in yield strengths of 355 MPa and 460 MPa. HISTAR® grades combine high strength with excellent toughness at low temperatures and outstanding weldability - these material properties were considered incompatible until now. The application of the innovative in-line heat treatment QST (Quenching and Self-Tempering) allows all HISTAR® grades, unlike most standard grades, to offer improved guaranteed values for yield strength over the whole product range. Considerable weight reduction and cost savings of steel structures Time savings in fabrication process: e.g. generally no preheating required for welding thanks to HISTAR®'s low carbon equivalent values HISTAR® high strength steels are the ideal solution for structural applications where strong axial behaviour is key. In the shape of hot rolled Super Jumbo profiles, HISTAR® steels lead to automatic cost and material saving compared to conventional steel grades in the following applications: In gravity columns (steel and composite columns with hot rolled profiles for higher resistance under axial compression, cruciform sections, and tailor-made solutions), the use of HISTAR® 460 compared to S355 brings an immediate 30% improvement of the axial stress resistance in relation to cost, weight savings, and gains in net carpet area. In long span trusses, the use of HISTAR® steels reduces the size and weight of its members, allowing for more economical and lighter designs.
