COSMOHARD – 600 R
Identification : Name Printed
Characteristics : A medium heavy coated, rutile based hardfacing electrodes for impact resistance with high hardness upto 620 BHN. The weld deposit Is non-machinable and can only be ground. A buffer layer of megas Is recommended on carbon steel. The electrode Is suitable for abrasion, Impact or a combination of both.
Applications : Drill bits, shears and croppers, crusher hammers,cater pillar treads, conveyor bucket, mixer blades, dipper teeth, cane cutter knives, crane wheels, metal cutting and forming tools etc.
Weld Metal Properties (%) :
C = 0.3to0.6 Mn =01 Max
SI = 0.5 Max Cr =4-6
