Flux cored welding electrodes comprise a iron based metal sheath and either a flux or metal core within the sheath, enclosing core ingredients. The core ingredients and sheath together comprise, in weight percentages based on the total weight of the electrode, very low levels of manganese. While having low levels of manganese the electrodes satisfy the strength and safety requirements required of commercial electrodes. Embodiments contain manganese in the range of 0.09 to 0.19% by weight of the electrode, along with other components.

Low manganese welding electodes

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 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.
