Unlimited buildup powder that's easily machinable. Its soft deposit fuses well with cast iron, thus avoiding the hard spots common with arc welding repair procedures. Also fuses with steels and nickel alloys. Used for casting buildup, machining errors on cams, keyways, glass molds, brake drums and water pump housings. The deposit has good corrosion resistance, low coefficient of friction, heat scaling resistance and excellent impact values. Use RC 30 or above for stainless steels.
