Product Description

Thermco50 Cobalt-Base Heat Resistant Alloy UMCo-50

 

 

UMCo-50 is a cobalt-chromium-iron heat-resistant alloy with good resistance to thermal shock, oxidatoin, and corrosion,  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.

 

For example, the alloy used for skid rails at a steel mill undergoes regular use at 1350°C,so other alloys could not be used due to their low melting point in the application related to heat treatments and furnaces. But UMCo-50 shows successful results.

Characteristics

High Temperature Resistance, Thermal Shock Resistance , Wear Resistance

Higher melting points than other cobalt based and nickel based alloys (1380 -1395 °C)

Corrosion resistant in Sparse sulfuric acid and boiling nitric acid and corrosion rapidly in hydrochloric acid

 

Shock Resistances

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 agents. Hardly any cracking occurred in UMCo-50, whereas the 25Cr-12Ni alloys were able to be used for only 8 months in average.
