incoloy825 summary
In conclusion, incoloy825 alloy plates have excellent corrosion resistance in fluorine gas, hydrochloric acid, sulfuric acid, hydrofluoric acid and their derivatives, and are more corrosion resistant than copper-based alloys in seawater. Incoloy825 alloy plate has excellent corrosion resistance, is often used in aerospace and industrial applications, and can also be used at temperatures above grade 1 to grade 4, it has good cold rolling properties.
The main feature of UMCO50 cobalt alloy is heat resistant, with excellent thermal shock resistance and wear resistance. It has also shown great strength, attacking sulfur and vanadium. Another feature is that it has a higher melting point than other cobalt-based or nickel-based heat-resistant alloys. For example, this alloy is used for anti-slip guides, which are often used in steel mills in 1350. Thus, UMCO50 shows successful results in applications that cannot be applied to other alloys due to its low melting point in heat treatment furnaces. When the impact resistance is given priority to UMCO-50 due to its thermal shock resistance, this alloy exhibits superior thermal shock resistance than the commonly used stainless steel 25Cr-20Ni. For example, even after 500 repeated cycles of heating and cooling (1000 - water cooling for 7 seconds), no cracking occurs. As a practical example, the alloy is used for four and a half years as a tray for up to 1,000 heating and quenching agents in a heavy oil furnace. Hardly any cracking umco-50 alloy produced while able to be used for as long as 8 months, homogeneous 25Cr-12Ni. Abrasion, anti-UMCO-50 wear resistance, hardly any deterioration was found after 50 months of copper sulfide as a sintered strip. On the other hand, iron castings are applied to such severe corrosion, oxidation and wear that even the operation was carried out 900 so that they could be used for as little as three and a half months.
