Alloy 347 is a stabilized, austenitic, chromium steel containing columbium which allows for the elimination of carbide precipitation, and, consequently, intergranualr corrosion. Alloy 347 is stabilized by the additions of chromium and tantalum and offers higher creep and stress rupture properties than alloy 304 and 304L which may also be used for exposures where sensitization and intergranualr corrosion are of concern. The addition of columbium also allows Alloy 347 to have excellent corrosion resistance, even superior to that of alloy 321. 347H is the higher carbon composition form of Alloy 347 and demonstrates improved high temperature and creep properties.
Alloy 347 is frequently used for the fabrication of equipment, which must be placed in service under severe corrosive conditions, and is also common to the petroleum refining industries. Applications that consistently used Alloy 347 include:
High temperature chemical processes
Heat exchanger tubes
High temperature steam service
High pressure steam pipes
Radiant superheaters
Boiler tubes
Heavy duty exhaust systems
General refinery piping
Corrosion Resistance:
Offers similar resistance to general, overall corrosion as Alloy 304
Used for applications where alloys such as Alloy 304 are vulnerable to intergranualr corrosion
Generally used for heavy welded equipment which cannot be annealed and for equipment which is operated between 800 to 150°F (427 TO 816°C)
Alloy 347 is preferred over Alloy 321 for aqueous and other low temperature environments
Primarily used in high temperature environments where resistance to sensitization is necessary, in turn preventing intergranualr corrosion at lower levels
Susceptible to stress corrosion cracking
Exhibits oxidation resistance similar to all other 18-8 austenitic stainless steels
