Celsius S460NH
Specification details for Celsius S460NH

EN-Construction-Product-Celsius hot finished hollow sections - Celsius S460NH | Key features

Key features
  • Fully normalized structural hollow sections, compliant with EN 10210:S460NH
  • High strength steel, enabling at least 20% weight saving and reduced carbon footprint, compared to an S460 strength section, when used in strength-limited applications
  • Normalized fine grain steel, so free of internal stresses and with a minimum strength of 460N/mm2 allowing the highest fabrication factors and enabling material cost savings and lighter structures
  • Available in a wide size range of square (40 x 40 x 3.2mm to 400 x 400 x 16mm) rectangular (50 x 30 x 3.2mm to 500 x 300 x 16mm) hollow sections
  • Tight corner radii (<2T) exceeding the standard - enhancing the product’s aesthetic appeal whilst avoiding the risk of brittle fracture which occurs in some cold formed products
  • Excellent dimensional consistency, high levels of formability, suitable for galvanising and, because the steel is fully-killed, excellent weldability
  • Fully compliant with CE marking and certified as suitable for all structural applications; overcomes design risks associated with other forms of hollow sections
  • Certified as suitable for mechanical applications, especially those involving cyclical loading
  • Suitable for low temperature applications (40J @ -20°C)
  • Batch-tested to give the properties of the specific delivered material; full test certification supplied
  • Clearly marked as Celsius® S460NH, and supplied with a 3.1 test certificate for the reassurance of batch traceability
  • Full technical support available

EN-Construction-Product-Celsius hot finished hollow sections - Celsius S460NH | Mechanical properties

Mechanical properties
