Hardox 450

Hardox 450 is an abrasion-resistant steel with a nominal hardness of 450 HBW. Hardox 450 combines good bendability and weldability with an option of guaranteed impact toughness (Hardox 450 Tuf). The products can be used in many different components and structures that are subjected to wear. Hardox 450, with an extra 50 Brinell hardness over our 400 grade, provides better dent and abrasion resistance as well as a longer wear life, so you can achieve even greater savings.

Hardness

  • 425 to 475 HWB
  • Hardness test Brinell, HBW according to EN ISO 6506-1. The test is carried out on a measuring surface which has been formed by milling (0.5 - 3.0 mm deep) of the sheet metal surface.

Dimension Range

  • Hardox 450 Sheet is available in thicknesses of 2.5 - 8 mm. Hardox 450 Sheet is available in widths of up to 1700 mm and lengths of up to 16000 mm. 
  • Hardox 450 Cold Rolled is available in thicknesses of 0.70 – 2.10 mm. The supplied width is 800 - 1500 mm and length 1000 - 8000 mm. 
  • Hardox 450 and Hardox 450 Tuf are available in thicknesses of 3.2-130 mm. For thicknesses over 80 mm the preferred width is 1650 mm.

Surface finish

  • According to EN 10 163-2, Class A Subclass 1. 

Fabrication and other recommendations

  • Hardox 450 and Hardox 450 Tuf are not designed for further heat treatment. Mechanical properties are achieved by quenching and, when necessary, by means of subsequent tempering. The properties of the delivery condition cannot be retained after exposure to temperatures over of 250 ºC.

Tolerances

  • Thickness: Tolerances according to SSAB‘s thickness precision guarantee AccuRollTech. – AccuRollTech meets the requirements of EN 10 029 Class A, but offers narrower tolerances.
  • Length and width: According to SSAB‘s dimension program. Tolerances conform to EN 10 029 or to SSAB‘s standard.
  • Shape: Tolerance according to EN 10 029.
  • Flatness: Tolerances according to SSAB‘s flatness tolerances which are narrower than EN 10 029 Class N (steel type L). 
  • Surface Properties: According to EN 10 163-2, Class A Subclass 1.
