16 Gauge Cold Rolled Steel Sheet Grade 347 2B Finish Custom Cut
16 Gauge Cold Rolled Steel Sheet Grade 347
Specifications: UNS S34700 / S34709
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.

Applications:
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
- Radiant superheaters
- Boiler tubes
- Heavy duty exhaust systems
- General refinery piping
