UMCo50 is a heat-resistant cobalt alloy that has excellent thermal shock resistance and wear resistance. It also shows great strength against sulfur-and vanadium-attacks. Another feature is its higher melting point compared to other cobalt base or nickel base heat-resistant alloys. For example, the alloy used for skid rails at a steel mill undergoes regular use at 1,350°C. Thus UMCo50 shows successful results in application relating to heat treatments and furnaces where other alloys could not be used due to their low melting point.
Since thermal shock resistance was given first priority when developing UMCo-50, this alloy shows far more outstanding thermal shock resistance than the popularly used 25Cr-20Ni stainless steel. For example, even after repeating the heating and cooling cycle (1000-water cooling-7 seconds) for 500 times, no cracking occurred. As a practical example, the alloy was used for four and a half years as a tray which was heated up to 1000 in a heavy oil furnace to quench various quenching.

Main characteristics
Thermal shock resistance
Due to the prioritization of thermal shock resistance in the development of UMCo-50 alloy, its thermal shock resistance is far superior to the widely used 25Cr-20Ni stainless steel. For example, even after 500 cycles of repeated heating and cooling (1000 water cooling -7 seconds), no cracks appeared. Application example: Heating to 1000 ℃ in a heavy oil furnace as a tray for quenching various quenching agents. UMCo-50 alloy has almost no cracking, while 25Cr-12Ni alloy can only be used for an average of 8 months.
Wear resistance
After 50 months of use as a sintered copper sulfide rod, the wear resistance of UMCo-50 has not decreased significantly. As a comparison, the cast iron parts used are severely corroded, oxidized, and worn, and even when operated at 900 ℃, they can only be used for three and a half months.
