Stainless Steel 347
Stainless 347 has low tantalum and cobalt and should be considered for nuclear applications. Stainless 321 is resistant to atmospheric corrosion, sterilizing solutions, many organic chemicals, and a wide variety of inorganic chemicals. Stainless 347 should also be considered for use in aircraft collector rings, and exhaust manifolds, expansion joints, and high temperature chemical process equipment.
