Nickel Alloy 20 Pipes and Tubes are popular in the chemical and petrochemical industries due to their exceptional properties. These alloys are composed of nickel, iron, chromium and copper, with varying levels of manganese, carbon and silicon. The combination of these metals gives Nickel Alloy 20 Pipes and Tubes their excellent corrosion resistance and high mechanical strength.
Nickel Alloy 20 Pipes Features:
Nickel Alloy 20 Pipes have a range of features that make them ideal for use in demanding industrial applications. Firstly, they have excellent corrosion resistance in harsh environments, including sulphuric and phosphoric acid. Additionally, they offer resistance to stress-corrosion cracking, general corrosion, pitting and crevice corrosion. Nickel Alloy 20 Pipes also have high mechanical strength and are tough enough to withstand high-pressure and temperature environments.

Nickel Alloy 20 Tubes Corrosion Resistance:
Nickel Alloy 20 Tubes are known for their high level of resistance to corrosion. They offer exceptional resistance to sulphuric acid, phosphoric acid, hydrochloric acid, and other aggressive agents. The corrosion resistance is largely due to the alloy's chromium, molybdenum, and copper composition. Nickel Alloy 20 Tubes also offer excellent resistance to corrosion caused by chloride stress and intergranular attack.
Nickel Alloy 20 Pipes Chemical Composition:
The chemical composition of Nickel Alloy 20 Pipes includes nickel, iron, chromium, copper, and small amounts of molybdenum, carbon, and silicon. The addition of copper in Alloy 20 Pipes helps to improve the alloy's resistance to corrosion, while the presence of nickel and iron gives the pipes increased strength and durability. The carbon content of the alloy is kept low to prevent intergranular corrosion, which can be problematic in high-temperature environments.
Nickel Alloy 20 Tubes Machining
Nickel Alloy 20 Tubes can be machined using traditional techniques similar to those used in machining other high-strength alloys. The common methods in use include: turning, drilling, threading, and milling. The alloy requires a slow and steady approach during machining to prevent work hardening and the utilization of liquid cooling agents to prevent the generation of excess heat. A high degree of care and skill is required during the machining process to prevent material damage.
