Characteristics
ALLOY625 is a low-carbon Ni-Cr-Mo-Nb alloy which shows excellent resistance to a variety of corrosive media.
?outstanding resistance to pitting, crevice corrosion, erosion and intergranular attack
?almost complete freedom from chloride-induced stress-corrosion cracking
?good resistance to mineral acids, such as nitric, phosphoric, sulphuric and hydrochloric acids
?good resistance to alkalis and organic acids
?good mechanical properties

Stock Form and Sizes
Corrosion Resistance
For optimal corrosion resistance the material must be in a clean condition and free from all kinds of contaminants before any fabricated component is placed into service. Under these conditions ALLOY625 exhibits excellent corrosion resistance in a wide variety of media:
?excellent resistance to pitting and crevice corrosion in chloride-bearing media
?essentially resistant to chloride-induced stress-corrosion cracking
?high resistance against impingement and erosion corrosion
?practically no corrosive attack in marine and industrial atmosphrers. High resistance to seawater and brackish water, even at higher temperatures
?high resistance against intergranular corrosion following thermal treatment and welding
The solution-annealed version (grade 2) shows good resistance to many corrosive gas atmospheres:
?good resistance to carburization and to oxidation under
?resistance to nitridation
?good resistance to halogen containing gases and to hydrogen chloride
Applications
The soft-annealed version of Nicrofer 6020 hMo (grade 1) is preferred for applications in the chemical process industry, in marine engineering and in pollution control equipment for environmental protection.
Typical applications are:
?superphosphoric acid production equipment
?nuclear waste reprocessing equipment
?sour gas production tubes
?piping systems and sheathing of risers in oil exploration
?offshore industry and marine equipment
?flue gas scrubber and damper components
?chimney linings
For high-temperature applications, up to approximately 1000 �C (1830 �F), the solution-annealed version of alloy 625 (grade 2) can be used in accordance to the ASME code for pressure vessels. For design calculations for equipment for use within the temperature range of approximately 500 ~ 1000 �C (930 ~ 1830 �F) the loss in ductility resulting from prolonged exposure within that temperature range must be kept in mind
?components in waste gas systems and waste gas cleaning plants exposed to higher temperatures
?flare stacks in refineries and offshore platforms
?recuperators and compensators
?submarine diesel engine exhaust systems
?superheater tubes in waste incineration plants
?cladding of waterwall sections and superheater tubes in waste incineration plants by overlay welding
