WEDOLiT FN 8471

Forming Agent

WEDOLiT FN 8471 is a pigmented, pasty yet flowable, water-insoluble special lubricant for cold forging operations of ferritic and SiCromAl steels. FN 8471 can also be used for dry expansion, preferably as external lubricant, without additional cooling. The lubricant must be applied by hand over the incoming mandrel bar.

  • Does not contain any chlorine compounds and is based on a well-adhering, temperature-stable mineral oil
  • Special basic pigments are used for the consistency adjustment
  • The special granulation size of the pigments allows an almost wear-free surface despite the high load
  • The extremely high pressure stability combined with exceptionally good adhesion of the lubricant, even on smooth surfaces, allows processes with large cross-sectional reductions
  • When processing Sicromal steels, the lumps must be pre-heated to approx. 200-280°C when entering the pilger machine
  • Strong adhesion and the high temperature stability are of particular importance
  • Pigments which remain after the annealing on the surface need to be removed before further processing by pickling in HCl or HNO3
