YAWATA Ni Cast 55 (Non-machinable Cast Iron)

YAWATA NI-55 now comes in small and economical-to-use size. The 2-piece vacuum pack will make sure that nothing goes to waste. It is a DIY favourite!!


Clssification : AWS A 5.15 : ENiFe-CI,  JIS Z 3252 : ECNiFe-CI,  DIN 8573 : E NiFe BG 23

Approvals : TIS

Application : Welding of normal cast irons and ductile cast irons.

YAWATA Ni Cast 55 is a graphite type electrode. Its Fe-Ni composit wire assures no excessive heating of electrode and no change of operational characteristics during welding. Deposited metal shows excellent mechanical properties and crack resistance.

1. Use dry electrodes only.  Damp electrodes should be re-dried at  80~120℃  for 60 minutes before use.
2. Preheating and postheating are not necessary in general. However,  preheating at 100~200℃ is required for a structure which is apt to cause stress cracks.
