Hochlegierte nichtrostende Stähle und Nickelbasislegierungen im Chemie-Apparatebau

High alloy stainless steels and nickel-base alloys in chemical equipment construction The new ferritic chromium steels and ferritic-austenitic steels, high alloy special austenitic steels and nickel-base alloys presented in recent years have by now yielded some years' positive industrial experience in several applications. The group of austenitic steels containing 6 wt.-% molybdenum are at the threshold for large size application in chemical equipment construction. The results of the first comparative investigations with other high alloy steels are rather promising. The spectrum of nickel-base alloys will certainly be complemented by Hastelloy alloy C-22, so that this alloy will be used in addition to titanium alloys in contact with strongly oxidizing media.
