The additively fabricated functionally gradient structures can be a potential replacement for conventionally manufactured structures via fusion welding techniques. A SS321/Inconel 625 functionally gradient material was processed by wire arc additive manufacturing (WAAM) process. The WAAM-formed SS321 comprises of equiaxed and …
321 Stainless Steel. 321 stainless steel (UNS S32100) is a titanium stabilized austenitic stainless steel that features improved resistance to intergranular corrosion. This grade is suitable for high-temperature applications up to 1500°F (815°C), where the addition of titanium stabilizes the material against chromium carbide formation.
AISI 321 stainless steel is a stabilized version of SS 304 but with titanium. The titanium content in SS 321 Stainless Steel helps it prevent carbide precipitation while welding in temperatures ranging between 800 – 1500°F. It also allows the alloy to barely elevated temperatures. Grade 321 stainless steel is highly resistant to oxidation
Re: SS 321 vs SS 316L. 01/08/2008 12:09 PM. The molybdenum gives 316 better overall corrosion resistant properties than Grade 321 (similar to 304, with Ti addition to improve temperature property within 800-1500 deg F), particularly higher resistance to pitting and crevice corrosion in chloride environments.
Grades 321 and 347 are the basic austenitic 18/8 steel (Grade 304) stabilized by Titanium (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. Grade 321 is the grade of choice for applications in the temperature
