Abstract
The laboratory results have demonstrated the positive effect of the input of fluorinated carbon additive and nickel into the composition of 25Kh5FМS cored wire for welding of rolls additives comprising. In particular, it was found that the use of material containing carbon and fluorine, instead of amorphous graphite reduces the deposited layer contamination by nonmetallic inclusions, and the input of nickel into the cored wire refines austenite grains and ensures the formation of fine carbides. Thus increases the thermal resistance of the deposited layer. The article describes the data on the hardness increase of the deposited metal layer with the increase of carbon equivalent of surfacing powder cored wire of 25Kh5FМS grade.
