OK 68.53
 
Super Duplex Electrode for Joining Non Weldable Steels
OK Selectrode 68.53 is a super duplex high-strengthhigh ductility [HSHD] electrode for variety of steel grades to be welded to themselves and to other grades. The range also includes steels developed in late nineties as SAF 2507, ZERON 100, Ferralium 255, UR 47N, DP3 and all hardenable and alloy steels.
 
It is to be used selectively where working conditions are extreme and demands very high stress and failure risk.
 
The deposit is resistant to stress corrosion, cyclic impact, dynamic loading and hydrogen cracking in heat affected zone. It is an all position electrode with good bonding performance with all industrial steel grades.
 
ALLOY BASE
Fe, Cr, Ni, Mo, Mn, N
 
SPECIAL FEATURES
  • Nitrogen bearing alloy for a combination of strength and ductility better than any other electrode so far developed
  • Universal compatibility with all steels
  • Resistant to dilution related problems
APPLICATIONS
Critical areas, which require extreme service performance, high life and/or are not weldable by any other welding techniques and consumables.
