Hardox 400

Hardox 400 is an all-round wear resistant plate. Due to its high toughness, good bendability and weldability, the plates can also be used for load bearing duties in certain applications.


Example of application

  • Front loaders
  • Dump trucks
  • Buckets
  • Barges

Testing


Brinell hardness, HBW according to EN ISO 6506-1, on a milled surface 0,3-3 mm below surface. 
At least per heat and 40 tons. The nominal thickness will not deviate more than + 15 mm from that of the tested 
plate.


Surface Conditions


Hardox 400 can be delivered in shot blasted and primer coated surface condition.


Dimensions


Hardox 400 is supplied in thicknesses of 3 -130 mm. For dimensions with width < 1600 mm and thickness 3-6 mm preferred widths are 1500 or 1600 mm, delivered as cut-to-length in as rolled surface condition with mill edge as standard. Cut edges is on option. Widths up to 3300 mm are available.



Tolerance


Thickness tolerances according to thickness precision guarantee AccuRollTech 
TM. - AccuRollTech TM meets the requirements of EN 10 029. Class A, but offers more narrow tolerances. For shape, length, width and fl atness the tolerances conform to EN 10 029 (Flatness, Class N). Widths < 1600 mm and thickness 3-6 mm the shape, length and width conform to EN 10 051, tighter tolerances on request.


Surface Properties


According to EN 10 163-2
- Requirements according to Class A
- Repair conditions according to Subclass 1.
