Jun 19, 2016 · Niobium-stabilized austenitic stainless steel 347H (SS 347H) is a candidate alloy of interest for the Gen IV SCWRs. In-depth understanding the 347 Stainless Steel Plate, Sheet, and Round BarThe 347 stainless steel grade is a stabilized alloy, due to its columbium + tantalum component within. Ideal for long-term work life in high temperatures (800-1500ºF), 347 Stainless Steel is also resistant to intergranular corrosion in the chromium carbide precipitation range.

347 Stainless Steel Sheet, Coil and Bar - AMS 5512, 5646

347 Stainless Steel Sheet, Coil and Bar - AMS 5512, 5646. 347 stainless steel is a columbium/tantalum stabilized austenitic chromium-nickel stainless steel. This material is stabilized against chromium carbide formation by the addition of columbium and tantalum. Since these elements have a stronger affinity for carbon than chromium, columbium Alloy 347/347H Heat Resistant Stainless Steel Plate

  • General PropertiesCorrosion ResistanceMechanical PropertiesAlloy 347 (UNS S34700) is columbium stabilized austenitic stainless steel plate with good general corrosion resistance and somewhat better resistance in strong oxidizing conditions than 321 (UNS S32100). It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 1500°F (427 816°C). The alloy has good oxidation resistance and creep strength to 1500°F (816°C). It also possesses good low temperature toughness.

    Type 347 steel may be required for the containment of strong mineral acids where type 321 might be subject to knife-line attack. An alternative solution to such Stainless Steel 347 - Alloy CompositionStainless Steel 347 - Alloy Composition. Stainless Steel 347 has slightly improved corrosion resistance over type 321 stainless steel in strongly oxidizing environments. Alloy 347 is a columbium (niobium)/tantalum stabilized austenitic chromium-nickel stainless steel which was developed to provide an 18-8 type alloy with improved intergranular Stainless Steel 347 Fittings - Gnee steelStainless steel 347 is a stabilized alloy whose specialty is the exceptional resistance to intergranular corrosion. Apart from that, it holds great level of strength and therefore can be used under high temperatures ranging from 800 to 1500° F (i.e. 427 to 816° C) in the chromium carbide precipitation.
