Product Description
Corrosion Resistant Stainless Steel Plate Grade 321 / 1.4541
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 range of up to about 900 °C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion.

Technical Notes
Grade 321H is a modification of 321 with higher carbon content to provide improved high-temperature strength. A limitation with 321 is that titanium does not transfer well across a high-temperature arc, so it is not recommended as a welding consumable. In this case grade 347 is preferred. Grade 321 does not polish well, so is not recommended for decorative applications.
