PerformanceTechnical information
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: 2019 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.
HISTAR® steels are produced in the modern EAF (Electric Arc Furnace) route, using 100% scrap as a raw material (upcycling). EAF steel production technology allows for significant reductions of noise, particle, and CO2-emissions and saves water and primary energy in the production process.

ConstructionResistant, 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
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. The same applies to belt trusses and outriggers, which improve stiffness and strength and add torsional resistance in high rise buildings. In foundation solutions, considerable weight savings are automatically ensured when using HISTAR® for HZ®-M King piles in axial compression.

Continental Steel and ArcelorMittal: partners for years
Through the ArcelorMittal International Singapore office, Continental Steel in Singapore purchased 6000 tonnes of XCarb® recycled and renewably produced sections in steel grade HISTAR® 460 / S460M for its stock. The sections are column sizes UC356x406 and HD400 ranging from 237 kg/m to 900 kg/m, which will be produced in the Differdange plant in Luxembourg.
Continental Steel will offer the first and largest stock of XCarb® recycled and renewably produced sections in South East Asia from their warehouse in Singapore. They are convinced their move will help to strengthen their market position in supplying sections to construction projects in the region.
Continental Steel and ArcelorMittal Europe – Long Products (through the ArcelorMittal International Singapore office) have been partnering for years already. As an example, ArcelorMittal HISTAR® beams are at the heart of the Jewel Changi Airport in Singapore. Today, thanks to their loyalty and trust, Continental Steel are helping to spearhead the South East Asian market with XCarb® recycled and renewably produced, which fits perfectly with the HISTAR® range. When lean design using high strength HISTAR® 460 sections is combined with XCarb® recycled and renewably produced steel, designers can drive low carbon solutions. Pairing a low embodied carbon manufacturing process with high strength steel can deliver very high carbon reductions.
ArcelorMittal's next joint projects with Continental Steel will be to deliver steel sections to upcoming major infrastructure developments like underground stations, expressways, and aviation hub expansion projects in Singapore. Pioneering with green steel and ArcelorMittal's XCarb® recycled and renewably produced sections is a step for Continental Steel towards gaining a competitive advantage.

ArcelorMittal steel awarded for its outstanding sustainability

In May 2022, ArcelorMittal International was awarded the highest rating at Singapore Green Building Council’s Leadership in Sustainability awards. The certificate acknowledges ArcelorMittal’s HISTAR® high strength structural steels for their outstanding sustainability due to the usage of 100% scrap steel and the EAF production route.
ArcelorMittal awarded the highest rating
In Singapore, as in many countries, the government is pushing hard for sustainability. Buildings in Singapore account for over 20% of carbon emissions and consume more than a third of the nation’s electricity. Singapore is already one of the most solar-dense cities in the world, but this is not enough. All efforts by companies, especially in the construction sector, must be encouraged and the most efficient solutions rewarded.
The Singapore Green Building Council’s Leadership in Sustainability awards recognise professionals, organisations, and construction projects that have made significant contributions to the development of a green, sustainable built environment.
ArcelorMittal International was among the 20 winners of the year and was awarded the highest rating.
Singapore Green Building certification for ArcelorMittal’s HISTAR®
ArcelorMittal International received the Singapore Green Building Product Certificate SGBP 4275 from Singapore Green Building Council for HISTAR®.
“This certification shows that ArcelorMittal is environmentally responsible. It is a great recognition for our efforts towards carbon neutral steel,” says Tan Yi Zhou, Technical Sales and Business Development, ArcelorMittal International. “I would also like to highlight that ArcelorMittal is the only steel supplier on the list that has structural steel beams and columns certified by SGBC with a 4-tick certificate.”
90% reduction with the perfect low carbon partners: HISTAR® and XCarb® recycled and renewably produced
ArcelorMittal International received the SGBP 4275 certificate for ArcelorMittal steel manufactured according to the ETA-10/0156 standard. With 100% scrap steel used in the electric arc furnace route, HISTAR® emits 524kg CO2/tonne for the life cycle analysis modules A1-A3.
ArcelorMittal can even go one step further in decarbonising HISTAR® steel products by manufacturing them with renewably produced electricity with the XCarb® recycled and renewably produced label. When lean design using high strength HISTAR® sections is combined with XCarb® recycled and renewably produced steel, designers can find the perfect low carbon solution. Pairing a low embodied carbon manufacturing process with high strength steel can deliver carbon reductions of up to 90% (for HISTAR® 460).
Therefore, the next step for ArcelorMittal International in Singapore is to obtain another certificate to differentiate XCarb® recycled and renewably produced (with its low CO2e emissions at 333kg CO2/tonne) from the current SGBP 4-tick certified steels at 524kg CO2/tonne.
