1.4845              310 S              21.3 x 2.77 - 219.1 x 12.7          1/2" SH40S - 8" SH80S

1.4878              321 H              21.3 x 2.77 - 219.1 x 12.7         1/2" SH40S - 8" SH80S

Non-magnetic, highly corrosion-resistant Cr-Ni-Mo-N steel

material:           AISI:               seamless:

1.3964              Alloy 50         33.7 - 219.1                                1" - 8" up to SH80S

Material 1.3964 is a nitrogen-enhanced, high-alloy Cr-Ni-Mo-N steel with excellent resistance to seawater, intergranular corrosion, and stress corrosion cracking. The alloy composition provides a significantly higher yield strength compared to conventional Cr-Ni-Mo steels and a stable austenitic microstructure that remains non-magnetizable even after cold working—with a relative magnetic permeability below 1.01.
