MMA Electrode Chrome-Nickel 308L 3.2x350 mm Bohler
Item internal code: 75300
Description:
Low carbon, core wire alloyed austenitic electrode with rutile-basic coating for use in all industries where similar type steels including higher carbon grades as well as ferritic 13% chromium steels are welded. This brand is noted for its outstanding welding characteristics, excellent weld ability on AC, and high hot cracking resistance of the weld metal. The main features of economic interest are excellent out-of-position weld ability, self-detaching slag with no residues, and moisture resistant coating. Resistant to intergranular corrosion up to 350°C.
