Nickle Alloy Welding Electrode E BK 625

Nickle Alloy Welding Electrode E BK 625 is used for Shield Metal Arc Welding (SMAW). Special high nickel base electrode for crack-free, welding of Inconel®, Incoloy®, Nimonic®, Monel®, and Hastelloy® alloys, as well as high alloyed stainless steel, heat resistant steel, and ferritic steel. The alloy is also used for making dissimilar welds between nickel alloys and steel, stainless steel and copper alloys, and between steel and copper alloys. The excellent mechanical characteristics at low temperatures make the alloy suitable for welding nickel-steels (9%Ni) for use at subzero temperatures (down to -196 °C. Deposits have superior corrosion resistance and are resistant to temperatures up to 1100 °C in sulfur-free atmospheres. Excellent welding properties: a stable arc even at low amperage.

_Applications

Heat resistant parts, where thermal shocks occur, installations for liquefied gas. Joining stainless to mild steel, welding crack-sensitive steel types even with heavy sections. Cushion layers for hard facings on problem steels
