Abstract (en)
Alloys containing 35.5-69% by weight of iron, 21-35% by weight of chromium, 10-25% by weight of nickel and 0.4.5% by weight of molybdenum as well as the customary accompanying elements, such as carbon, silicon, manganese, phosphorus, sulphur, copper, cobalt, aluminium, vanadium, titanium, tantalum and/or niobum can be used as materials for articles which are resistant to nitric acid up to a concentration of about 75% in the temperature range from the melting point of the nitric acid to 150<o>C.
