Both 347 and 321 offer good resistance to polythionic acid stress corrosion cracking, encountered in oil refineries. The high temperature oxidation resistance of 347 is similar to that of 304 stainless steel. Useful to 1500°F. Often in many product forms, the grain size and carbon content can meet both the 347S and 347H requirements.
347 stainless steel is a variant of the basic austenitic 18/8 Grade 304 with added Columbium. The steel has excellent toughness at cryogenic temperatures. +44 (0)1675 437 733 347 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. High creep and stress rupture properties are part of their superior

The next level of defense is to use chemically stabilized grades of stainless steel like Types 321 and 347. For these stainless steels Ti (Type 321) or Cb (Type 347) is added. The intent is for titanium or columbium carbides to form leaving chromium in solution. However, some chromium can still be precipitated when the alloy is heated in the Stainless Steel Grade 347H (UNS S34709)Machining grade 347H stainless steel is slightly tougher than that of grade 304 steel. However, the hardenability of this steel can be minimized by the use of constant positive feeds and slow speeds. Welding. Grade 347H stainless steel can be welded using most of the resistance and fusion methods.
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 Used for heavy welded equipment when annealing is not possible Good oxidation resistance, on par with most other austenitic stainless steels Higher Stainless Steel Alloy 347H - Continental Steel & Tube CompanyType 347H is a high carbon austenitic chromium stainless steel.

Type 347. For this reason, Type 347 is preferable for aqueous and other low temperature environments. Exposure in the 800 to1500°F (427 to 816°C) tempera-ture range lowers the overall corrosion resistance of Type 321 to a much greater extent than Type 347. Types 347 and 348 are used primarily in high tempera- What is 347 Stainless Steel? - Definition from CorrosionpediaDec 28, 2016 · Type 347 is designed to have properties similar to type 304 stainless steel, which is the most common grade of austenitic stainless steel. The most notable difference is its ability to resist intergranular corrosion. This resistance to intergranular corrosion makes type 347 particularly well suited for welding applications.
347 347H Stainless Steel are austenitic chromium steels containing columbium. 347 347H Stainless Steel are recommended for parts fabricated by welding which cannot be subsequently annealed. These types also are used for parts which are intermittently heated and cooled to temperatures between 800°F and 1600°F.
