Delivery Condition :

  • Delivery Condition is Q or QT ( Quenched or Quenched and Tempered ). The plates are delivered with sheared or thermally cut edges. Untrimmed mill edges are abailable by agreement. Width ≤1600 mm and thickness 3 – 8mm ober 80mm are delivered with mill edge as standard.
  • Delivery requirements can be fond in SSAB's brochure 41 – General product information |Strenx, Hardox, Armox and Toolox -UK or at WWW.SSAB.COM.

 

Fabrication and Other Recommendations :

  • Welding , bending and machining
  • Recommendations can be fond in SSAB's brochures www.hardox.com
  • Hardox 400 is not intended for further heat treatment. It has obtained its mechanical properties by quenching and when necessary by means of subsequent tempering. The properties of the delivery condition cannot be retained after exposure to temperatures in excess of 250 °C.
  • Appropriate health and safety precautions must be taken when welding, cutting, grinding or otherwise working on this product. Grinding, especially of primer coated plates, may produce dust with a high
