Thermal Shock Resistance Alloy UMCO50 <\/b><\/p>\n

XUNSHI NEW MATERIALS CO LTD supplies UMCO50 in forms of forgings, round bar, tube and so on.<\/p>\n

UMCO50is a heat-resistant cobalt alloy with excellent thermal shock resistance and wear resistance performance. It has great strength against sulfur-and vanadium-attacks. UmCo-50 has higher melting point compared to other cobalt based or nickel based heat-resistant alloys.<\/p>\n

UMCO50 is suitable for the environments that require oxidation resistance,high temperature strength and thermal corrosion resistance, thermal impact resistance and wear resistance.<\/p>\n

In a sulfur-containing oxidation atmosphere, it has an excellent thermal corrosion resistance to heavy oil or other fuel combustion medium. It is widely used in coal chemical nozzle.<\/p>\n

For example, the alloy used for skid rails at a steel mill undergoes regular use at 1350\u00b0C. <\/p>\n

Other alloys could not be used due to their low melting point in the application related to heat treatments and furnaces. But W.Nr. 2.4778 shows successful results.<\/p>\n

Shock Resistances<\/b><\/p>\n

Since thermal shock resistance was given first priority when developing W.Nr. 2.4778, 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 agents. Hardly any cracking occurred in W.Nr. 2.4778, whereas the 25Cr-12Ni alloys were able to be used for only 8 months in average.
