HARDOX® 450

    INFORMATION:

     

    Hardox® 450 is the most popular abrasion-resistant steel with excellent structural properties. Combines good bendability and weldability with an option for guaranteed impact toughness.

     

    The products can be used in many different components and structures that are subject to wear. Hardox® 450, with an extra 50 Brinell hardness over our 400 grade, provides better dent and abrasion resistance as well as longer wear life, so you can achieve even greater savings.

    SPECIFICATIONS:

     

  • Nominal hardness of 425 – 475 HBW
  •  

  • Thickness tolerances according to Hardox® Thickness Guarantees. Hardox® Guarantees meet the requirements of EN 10 029 Class A for plate. For sheet, the guarantees meet the requirements of 1/2 EN 10 051 and EN 10 131 for cold rolled sheet products
  •  

  • Length and width according to SSAB’s dimension program. For plate, the tolerances are according to SSAB´s mill edge standard or tolerances that conform to EN 10 029 and EN 10 131 for cold rolled sheet. Tolerances conform to EN 10 051 for sheet, tighter tolerances available on request
  •  

  • Shape tolerances according to EN 10 029 for plate, EN 10 051 for sheet and EN 10 131 for cold rolled sheet
  •  

  • Flatness tolerances are according to Hardox® Flatness Guarantees Class D for plate, which are more restrictive than EN 10 029. For sheet, the tolerances are according to Hardox® Flatness Guarantees Class A, that offer narrower tolerances compared to EN 10 051. Cold rolled sheet tolerances are according to Hardox® Flatness Guarantees Class B
  •  

  • Surface properties according to EN 10 163-2, Class A Subclass 1
  •  

  • Bendability for plate is according to Hardox® Bending Guarantees Class E. For sheet, the bendability is according to Hardox® Bending Guarantees Class C for cold rolled sheet and Class B for sheet
