DESCRIPTION

COBALT THREAD TAPS ARE AN ALLOY OF HSS AND COBALT. THEY ARE MORE RESISTANT TO HEAT AND WEAR THAN HSS TAPS, MAKING THEM SUITABLE FOR USE ON HARDER MATERIALS. THE HIGH TEMPERATURE RESISTANCE, HARDNESS AND WEAR CHARACTERISTICS OF COBALT WHEN ALLOYED WITH OTHER METALS ARE PUT TO GOOD USE IN SUPERALLOYS FOR GAS TURBINES AND AS HARD SURFACING IN CRITICAL APPLICATIONS WHERE WORKING ENVIRONMENTS ARE AGGRESSIVE (HOT, PRESSURISED AND/OR ACIDIC).
