Wear Resistance of Corrosion-Resistant Austenitic High-Nitrogen Steels 05kh22ag15n8mf and 02kh22ag10n4mf in a Cryogenic Environment

Wear tests were carried out under dry sliding friction conditions in a cryogenic environment on corrosion-resistant high-nitrogen austenitic steels 05Kh22AG15N8MF (0,50% N) and 02Kh22AG10N4MF (0, 55% N), as well as nitrogen-free steels 08Kh18N9T and 03Kh17N13M2. It was established that in terms of wear resistance at increased (7,5 m/s) sliding speed in a self-mated system, high-nitrogen steels 05Kh22AG15N8MF and 02Kh22AG10N4MF surpass steels 08Kh18N9T and 03Kh17N13M2 due to greater solid solution and strain hardening.
