347 Stainless Steel Bar - (annealed condition) TW Metals

347 stainless is an austenitic stainless steel offering an excellent resistance to inter-granular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500O F. Alloy 347 alloyed with columbium-tantalum (referred to as niobium) allows good mechanical properties at high temperatures. 347 Stainless Steel Pipe347 Stainless Steel Seamless 347 Stainless Steel Pipe is columbium stabilized austenitic stainless steel pipe 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).

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-tantalum carbides precipitate within the grains instead of forming at the grain boundaries. 347 should be considered for 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. 347 Stainless Steel UNS S34700 UlbrichType 347 is a stabilized austenitic stainless steel similar to type 304 with an addition of Columbium and Tantalum. The columbium serves to produce a stabilized type of stainless steel which is immune to chromium carbide precipitation. Alloy 347/347H Technical Information347/347H. * The columbium plus tantalum content shall not be less than 10 times the carbon content and not more than 1.0% Note:347H requires the columbium plus tantalum content to be not < 8 times the carbon content and not > 1.0%.

    Stainless 347 1.888.282.3292 UPMET.COM. 347 is a stabilized stainless steel that offers excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F. It is stabilized by the addition of columbium and tantalum. Stainless Steel Grade 347H (UNS S34709)Sep 12, 2012 · Grade 347H stainless steel can be readily stamped, blanked, spun and drawn as it is quite tough and ductile. Annealing. Grade 347H stainless steel can be annealed at temperature ranging from 1010 to 1193°C (1850 to 2000°F) and then quenched with water. Hardening. Grade 347H stainless steel is unresponsive to heat treatment. Stainless Steel - Grade 321 (UNS S32100)Oct 23, 2001 · Grades 321 and 347 are the basic austenitic 18/8 steel (Grade 304) stabilized by ium (321) or Niobium (347) additions. These grades are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850 °C.

    Stainless Steel Alloy 347H Type 347H is a high carbon austenitic chromium stainless steel. Found in applications that demand high temperature resistance, other major design features include:Similar resistance and corrosion protection as Alloy 304 Technical Data BLUE SHEET - METSERVETypes 321, 347 and 348 stainless steels are also advantageous for high temperature service because of their good mechanical properties. Types 321, 347 and 348 stainless steels offer higher creep and stress rupture properties than Type 304 and, particularly, Type 347/347H Stainless Steel - Penn StainlessAlloy 347 is a stabilized, austenitic, chromium steel containing columbium which allows for the elimination of carbide precipitation, and, consequently, intergranualr corrosion.
