Structural steel grades
Advantages of HISTAR® by applicationMore
HISTAR® steels are delivered in a thermomechanically rolled condition in accordance with the European Technical Approval ETA-10/0156. They comply with the requirements of the European standard EN 10025-4: 2004 for weldable fine grain structural steels and other national standards like ASTM A 913-11 and JIS G 3106:2008.
HISTAR® grades are compatible with the requirements of the Eurocodes for the design of steel structures and composite steel-concrete structures.
The steels are typically delivered with an Si content ranging between 0,14% and 0,25% and are as such capable of forming a zinc layer during hot-dip galvanisation. As the phosphorus content of these steels is usually lower than 0,035%, it does not have any influence on the final thickness of the coating in the considered Si range.
Resistant, economical, & sustainable
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

Landmark 81: ArcelorMittal supplies steel columns for Vietnam’s tallest tower3 September 2018
Ho Chi Minh City is the fastest economic growing urban area in Vietnam. Landmark 81 will be a particularly impressive addition to the city’s skyline once complete in early 2019 overtaking Keangnam Hanoi Landmark Tower as the country’s tallest. This 81-storey residential structure will offer luxurious living combining extraordinary views with maximum floor space thanks to 3600 tonnes of HISTAR® 460 sections produced by ArcelorMittal Europe. The tower will be a notable achievement for ArcelorMittal too. For the first time, we will be the sole steel supplier of all the sections in a high-rise.Project News
Sustainable building thanks to high strength steels
Sustainability is playing an increasingly important role in building. However, this concept is not just restricted to ecological issues, but also comprises economic and socio-cultural aspects. Only structures which fulfill all of this criteria are permanently successful and therefore sustainable.Article
