Abstract

Det er beskrevet anvendelse av plastiske- og støpe- materialer samt sveisetilsatsmaterialer av austenittiske jern-nikkel-krom-sillsium-legeringer for bygningsdeler som kommer i kontakt med varm, konsentrert svovelsyre eller O til 10 vekt-* oleum. Det er videre beskrevet en fremgangsmåte for frem- stilling av svovelsyre som er kjennetegnet ved at visse apparaturdeler består av den nevnte legeringen.
