Alloy 600 Tubing

Alloy 600 is an excellent candidate for many uses in extremely high temperature and highly corrosive environments. The blend of nickel and chromium yields a solid resistance to oxidation in operating temperatures. These temperatures can range from cryogenic to scorching levels of 2,000°F. The high nickel content of alloy 400 also offers a nearly-complete resistance to stress corrosion cracking, which is commonly found in chloride environments.

It is important to note that the chromium portion of the alloy’s chemical profile makes it possible for the grade to withstand high temperatures. The finer grain structure of the cold finished tube, additionally, brings better corrosion resistance, which includes higher fatigue and impact strength values.

Industry Applications

Aerospace
Alloy 600 is an excellent material for high-temperature applications requiring a combination of heat and corrosion resistance and is often found in turbine elements. See aerospace for more information.
Chemical Process
The higher levels of nickel and chromium in alloy 600 extends its suitability into the oxidizing range, placing it as a great candidate to resist organic acids. It is used extensively in the production of fatty acids seen in the chemical processing industry.
Fabrication
Alloy 600 is used in furnaces for instrumentation tubing, thermocouples and other sensors when high-temperature operations preclude the use of stainless steel alloy tubing. See fabrication for more information.
Oil & Gas
Due to its excellent corrosion resistance, alloy 600 is commonly used in subsea and offshore applications including sour gas well environments. See oil and gas for more information.
Power Generation
Alloy 600 is widely used in nuclear heat exchangers because it is resistant to steam at high temperatures as well as salt and caustic solutions. See power generation for more information.
Pulp & Paper
Alloy 600 tubing offers more resistance than stainless steel in white liquor heat exchangers where it excels in the presence of unevaporated liquor. See pulp and paper for more information.
