High boron hardfacing electrode

Electrodes for depositing hardfacing alloys containing boron, carbon, chromium, manganese, and silicon on the surface of metal components that are subjected to high thermal and mechanical stresses. The deposited hardfacing alloys have from about 2.5 to about 14.0 atomic weight percent boron and have...

Zusammenfassung:	Electrodes for depositing hardfacing alloys containing boron, carbon, chromium, manganese, and silicon on the surface of metal components that are subjected to high thermal and mechanical stresses. The deposited hardfacing alloys have from about 2.5 to about 14.0 atomic weight percent boron and have a hardness on the Rockwell "C" scale of at least about 65 HRC in the first layer of the weld deposit.
