Product Description

UMCo-50 With High Temperature Thermal Shock And Wear Resistance

UMCo-50 Co50 with High Temperature Thermal Shock and Wear Resistance

 

UMCo50 is 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.

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.

 

​UMCo-50 (Co50) is suitable for the environments that require oxidation resistance,high temperature strength and thermal corrosion resistance, thermal impact resistance and wear resistance.

 

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.

Main 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.

 

Wear Resistances

As for the wear resistance of UMCo-50, hardly any deterioration was found after being used as a sintering bar for copper sulfide for 50 months. On the other hand, cast iron parts used till then were heavily corroded, oxidized and worn even though operations were conducted at 900, making them usable for only three and a half months.
