Heat Treatment Nickel Alloy Forged Ring Incoloy 825/925/800 in Nuclear Industrial
Incoloy 825, 925, and 800 are part of the family of nickel-iron-chromium superalloys known for their high resistance to corrosion and high-temperature environments. The following are specific details regarding these alloy rings:
-
Incoloy 825: This alloy is particularly resistant to sulfuric and phosphoric acids and is often used in chemical processing, oil and gas recovery, acid production, and pickling operations.
-
Incoloy 925: With the addition of titanium and aluminum, this alloy has enhanced strength and hardness. It is primarily used in high-strength piping systems, pumps, and valves in the oil and gas industry.
-
Incoloy 800: Known for its resistance to oxidation and carburization at high temperatures, this is one of the most versatile Incoloy alloys. It is used in a variety of applications including heat treatment furnaces and chemical and petrochemical processing.
Each ring is forged using a process where the metal is heated before it's shaped to the desired dimensions and specifications. This not only ensures a more uniform internal structure but also results in greater strength and reduced stress.
After forging, the rings undergo a series of tests to confirm their dimensional accuracy and mechanical properties such as tensile strength, yield strength, hardness, and elongation.
In summary, Incoloy 825, 925, and 800 alloy rings offer excellent strength, corrosion resistance, and durability, making them ideal for high-stress, high-temperature, and corrosive environments.
