Due to the high Niobium content this alloy offers very good resistance against
abrasion by minerals, all weld metal requires no buffer layer except on materials
considered critical or old hardsurfacing layers. In this Situation Ceweld 735B,
ER 100 S1 or OA MnCr is recommended.
Suited for wear parts subject to medium impact and shock.
In critical cases such as cement rollers the interpass temperature should be kept
at 270ºC for the best results. The weld metal is only machinable by grinding.
