Abstract
A hard-facing material source is an article whose net composition is, in weight percent, from about 20 to about 35 percent chromium, from about 2 to about 5 percent boron, from about 1 to about 2.5 percent silicon, from 0 to about 0.5 percent carbon, from about 0.5 to about 2 percent manganese, and from about 0.2 to about 1.0 percent titanium, balance iron and incidental impurities. The article may be a powder or a hollow tube with a powder packed therein. The hard-facing material source is thermally applied to a substrate by spraying or welding.
