A ferric-austenitic CrNiMoN steel alloy to be used as material to manufacture welded components

Creators

Description

A chromium-nickel-molybdenum-nitrogen steel alloy (ferritic-austenite) is used to manufacture welded articles which without thermal treatment are resistant to pitting corrosion, intergranular corrosion (Monypenny-Stauss test) or boiling in 65% nitric acid with subsequent cross-breaking test. (IHOE)

Abstract (German)

Eine Chrom-Nickel-Molybdaen-Stickstoff-Stahllegierung (ferritisch-austenitisch) wird zur Herstellung von geschweissten Gegenstaenden, die ohne Waermenachbehandlung gegen Lochfrasskorrosion, interkristalline Korrosion (Monypenny-Stauss-Versuch) oder Kochen in 65%iger Salpetersaeure mit anschliessendem Biegeversuch bestaendig sind, verwendet. (IHOE)
