DUROID 250  
 
Machinable Build-up Prior to Hardfacing
A smooth running rutile coated general-purpose harclfacing electrode, depositing a tough air-hardening alloy weld metal, suitable for resisting moderate friction, abrasion and impact.
 
ALLOY BASE
Fe, Cr, Mn
 
SPECIAL FEATURES
  • Smooth arc with low spatter
  • Normally machinable weld metal
  • Deposits a weld with self-lifting slag
APPLICATIONS
Track links, rollers and sprockets, ropeway pulleys, trunion wearing plates, gears, shafts and general reclamation of all worn out carbon steel parts requiring subsequent matching. Other applications are pump housing, rail ends (medium Mn steel) for railways and tramways, forging dies, wheels, axles and couplings.
 
Suitable for use as a supporting buffer between a top layer of harder weld metal and a soft mild steel base. Recommended for hardfacing components and machine parts, which must be easily machinable after hardfacing.
