Abstract
Provided are improved nickel-based surfacing alloys containing from about 0.2% to about 5.0% by weight of either or both hafnium and niobium to the total alloy weight and iron-based surfacing alloys containing the combination of about 1.5% to about 2.5% by weight carbon in conjunction with from about 1.0% to about 2.5.% silicon whereby both types of alloys are characterized by having reduced porosity arising during the process of depositing them in a molten state by a weld surfacing process upon a nitrogen containing steel substrate.
