Corrosion resistance problems of low-magnetic shipbuilding steels

Resumo

The paper presents results of comparative studies of corrosion resistance and corrosion-mechanical strength for low-magnetic shipbuilding steels of alloying systems Mn–C, C–Mn–Ni, Cr–Ni, Cr–Ni–Mo, and Cr–Ni–Mn–N, produced using various hardening mechanisms. It is shown that nitrogen-containing steels developed by CRISM Prometey constitute new constructional material superior in resistance to corrosion cracking in seawater compared with low-magnetic steels used in shipbuilding nowadays.
