COSMOCAST -NM

Classification   :   AWS  :     Est

Characteristics : A medium heavy coated graphite based electrode for non-machinable welds on cast Iron. The electrode should be preferred when a strong and rigid joint Is to be obtained between two cast Iron parts. Very good abrasion resistence Is shown by the weld metal.

Applications : COSMOCAST NM suitable for welding of cast iron,cast steel machine parts and equipment and for all types of general reclaimation or repair work where machinability of the weld Is not essential. It Is excellent for joining cast Iron to mild steel.
