MARUTHI – NM NONMACHINABLE

MARUTHI – NM NONMACHINABLE is an unmachinable electrode producing smooth, dense, high strength & porosity free deposits even on old and dirty cast iron materials. The welds have good bond strength & slag detachability. Can be used in all positions, with deposits closely matching cast iron in color. Preheating in not necessary but, preheating to about 175 ̊C helps to reduce stresses and permits use of low amperage to reduce distortion.
