Material Overview
Grades 321 and 347 are austenitic 18/8 steels (based on Grade 304) stabilized by Titanium (321) or Niobium (347) additions. These grades resist intergranular corrosion after heating within the carbide precipitation range of 425-850°C. Grade 321 is ideal for applications up to 900°C, offering high strength, scaling resistance, phase stability, and subsequent aqueous corrosion resistance.
Grade 321H features higher carbon content for improved high-temperature strength. Note that titanium doesn't transfer well across high-temperature arcs, making grade 347 the preferred welding consumable for 321 materials.
