Description
Stainless Steel 321
Grades 321 and 347 are the basic austenitic 18/8 steel (Grade 304) stabilized byTitanium (321) or Niobium (347) additions. These grades are used because they arenot sensitive to intergranular corrosion after heating within the carbideprecipitation range of 425-850 °C.
