This alloy offers very good resistance against general abrasion and heavy
shock, all weld metal requires no buffer layer except on materials considered
critical or old hardsurfacing layers.
In this Situation OA 4370, ER 100 S1 or OA MnCr is recommended.
Suited for wear parts subject to strong impact, abrasion and shock.
In critical cases the interpass temperature should be kept at 270ºC for the best
results. The weld metal is only machinable by grinding.
