Industeel can make heavy ingots up to 130t unit weight in a full range of special steel chemistries. These ingots are then transformed into extra-heavy plates through a unique combination of hot forging and hot rolling to ensure:

  • Excellent internal plate quality
  • Narrow flatness and good dimensional tolerances
  • Good surface quality

 

Industeel ‘s flame-cut machining facilities then allow these heavy plates to be cut to shape irrespective of thickness based on your drawings.

A full and extensive offer:

  • Extra-heavy forged plates up to 800 mm thick, 4.3 m wide and 75 t unit weight
  • Precision flame-cut pieces with excellent tolerances and a wide range of shapes to provide products close to final dimensions
  • Excellent metallurgical properties as guaranteed by Z35 through thickness tensile testing and UT inspection, thanks to the structural isotropy and homogeneity achieved through the forging and rolling process
  • Excellent flatness and surface condition tolerances typical of plate products
