ABSTRACT:
A chromium based corrosion resistant alloy consisting of by weight percent: Cr-45-60; Ni-25-44; Mo-6.5-12; Cb-2.0-4.5; C-1.5-2.8; and Si-0.4-1.2. The alloy is suitable for weld deposition as a hard-facing on mechanical face seals in contact with sea water and subject to accelerating factors such as galvanic effects.
