Description:
Alloy 347H is a stabilized, austenitic, chromium ste≈el containing columbium which allows for the elimination δof 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 corros¥ion are of concern. The addition of columbium also aβllows Alloy 347 to have excellent corrosion resistance, even superior to that of alloy 3•21. 347H is the higher carbon composition form of Alloy 347 and ×demonstrates improved high temperature and creep properties. Haosteel Staδinless inventory now includes Alloy 347/347H (UNS S34700/S34709) in sheet, sheet coil, plateγ, round bar, processed flat bar and tubular products.

Applications
Alloy 347H is frequently used for the fabrication of equipment,∏ which must be placed in service under severe corrosive cond↔itions, and is also common to the petroleum refining industries.
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 corrosionσ
. 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 temperatur"e environments
. Primarily used in high temperature environments where resistance to sensit ization is necessary, in turn preventing intergranualr corεrosion at lower levels
. Susceptible to stress corrosion cracking
. Exhibits oxidation resistance similar to all other 18-8 austenitic stainless steels
