Summary for ss304 pharmaceutical manufacturing Discussion
SS304 in pharmaceutical manufacturing is generally considered acceptable for product-contact equipment such as milling machines for oral solids and tablet presses, according to T.S.N. Sankara Narayanan. He says both 304 and 316 are generally suitable for this kind of service, but they should be passivated before commissioning. The question from Dr. Siham Alhasan asked specifically whether SS304 can be used in contact with pharmaceutical product during manufacturing. The answer does not draw a sharp distinction between 304 and 316 for this application, but it does emphasize proper surface treatment and startup preparation. No conflicting views appear in the excerpt, and the practical takeaway is that SS304 can be used, provided the equipment is properly passivated before use.
Q. Is SS304 used in contact with pharmaceutical product during the manufacturing process like the milling machine for oral solids production or for tablets press?
Thanks

A. I agree with Dailey. Since your process involves milling, make sure that the passivation quality is adequate and ensure the same periodically.
