347 stainless aerospace tubing is made from an austenitic stainless steel offering an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500° F (427 to 816°C). 347 Stainless Aerospace Tubing - MI-L-T 8808, MIL-T-8606 347 stainless aerospace tubing is made from an austenitic stainless steel offering an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500° F (427 to 816°C). 347 Stainless Steel Bar - (annealed condition) TW Metals347 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 Pipe and Tube Packing347 Stainless Steel Seamless Pipes and Tubes is sleeved into plastic bag individually, pieces wrapped with water-proof material, bundled with nylon rope. Clear labels are tagged on the outside of the package for easy identification of the quantity and product I.D. 347 Stainless Steel Tubing - 347 High Temperature SS We offer 347 stainless steel tubing which is similar to type 321.. Although 347 high temperature SS tubes are similar to 321 in many ways, the addition of tantalum and columbium (niobium) reduces intergranular corrosion at high temperatures. 347 stainless steel tubing is often used in applications requiring repeated heating in the range of 800 - 1650 F (427-899 C) such as expansion joints 347 and 347H Stainless Steel Plate - Penn Stainless347 and 347H stainless steel plate is a general purpose austenitic stainless steel with a face centered cubic structure. It is non-magnetic in the annealed condition and can only be hardened by cold working. Niobium has been added to suppress grain boundary chromium carbide precipitation. 347H is the higher carbon version of 347 plate. Due to
AISI 347 stainless steel has an Electrical Resistivity of 72 Microhm-cm at 20 °C. Very good resistance to corrosion is exhibited by AISI 347 stainless steel, in fact, it is comparable with 304 stainless steel. 347 stainless steel is used in many industries like petroleum refining, chemical processing, waste heat recovery, food processing, etc. 347/347H Stainless Steel - Penn StainlessHome / Resources / Product Information / Stainless Grades / 300 Series / 347/347H Stainless Steel 347/347H Stainless Steel Penn Stainless inventory now includes Alloy 347/347H (UNS S34700/S34709) in sheet, sheet coil, plate, round bar, processed flat bar and tubular products. Alloy 347 - Stainless steels - NeoNickelAlloy 347 is generally used where corrosive conditions are severe, such as aircraft exhaust stacks, manifolds and ring collectors. Type 347 is also used for heavy welded assemblies which cannot be annealed after welding or where the operating conditions cause exposure within the temperature range between 426.67° to 815.55°F.
Alloy 347 does not perform well in chloride solutions, even in small concentrations, or in sulfuric acid. Fabrication Data Alloy 347 can be easily welded and processed by standard shop fabrication practices. Machining The cold work hardening rate of 321 makes it less machinable than 410 stainless steel Stainless Steel 347H - SS 347H Latest Price, Manufacturers 347 stainless steel plate in thicknesses from 3/16" through 4".

Stainless Steel Alloy 347 Material Solutions. Stainless 347 has low tantalum and cobalt and should be considered for nuclear applications. Stainless 321 is resistant to atmospheric corrosion, sterilizing solutions, many organic chemicals, and a wide variety of inorganic chemicals. Stainless 347 should also be considered for use in aircraft 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.
