Beschreibung
Zusammenfassung:	PURPOSE:To enhance the corrosion resistance of stainless steel parts to a nitric acid solution, by containing a specific amount of Si in stainless steel parts for handling a nitric acid solution containing a heavy metal or a compound thereof while forcibly adding NOx gas to the above mentioned nitric acid solution. CONSTITUTION:Because nitric acid containing a heavy metal such as Pt, V, Ce, Ru, U or Pu or a compound thereof has strong corrosive force to usual stainless steel, stainless steel containing Si
