Postalloy® DuraHard™ PS158Ti-FCO

Postalloy® DuraHard™ PS158Ti-FCO is a large diameter, non-cracking flux-cored, open-arc hardfacing wire that deposits a martensitic alloy with a high volume of finely dispersed Titanium Carbides (TiC). It has excellent abrasion resistance under low and high stress conditions and retains hardness at high temperatures. Crack-free deposits are possible with proper procedures. Use on carbon and low alloy steels. Large diameter wire is generally more alloy rich then smaller diameter wire.

  • Excellent welding characteristics..
  • Multiple layers maintain their hardness and abrasion resistance..
  • Produces full slag coverage that does not require removal between passes. Slag is easily removed with a chipping hammer.
  • Deposits are crack-free even after multiple layers.
