Boilers, superheater tubing and high-temperature turbine auxiliary systems.
Seawater piping, desalination plants and saltwater-cooled heat exchangers.
High-purity production equipment and sanitary processing systems.
Performance in acids, chlorides and reducing environments beyond the capability of many stainless steel grades.
Selected nickel alloys maintain mechanical strength, oxidation resistance and dimensional stability across severe operating temperatures.
Established forming, machining and fabrication practices support their use in demanding gasket manufacturing applications.
Nickel alloy products are available under applicable ASTM, ASME, EN, DIN and JIS material specifications.
Nickel and special alloys are selected when the process media, temperature, chloride content or corrosion mechanism exceeds the resistance or mechanical capability of conventional stainless steel grades.
The appropriate grade depends strongly on the specific chemical environment. Nickel-molybdenum-chromium alloys are commonly selected for highly aggressive mixed oxidizing and reducing environments, while specialized materials such as tantalum and zirconium are used for particular severe chemical services.
Inconel 600, 601, 602CA, 625, 718 and the 800-series grades are commonly considered for elevated-temperature applications, with the correct selection depending on temperature, atmosphere, mechanical loading and exposure duration.
