Got a marine application with saltwater exposure, will 316 stainless hold up better than regular stainless for plugging off unused ports?

Answer by: Customer Support on Sep 7, 2025, 7:50 AM

Grade 316 stainless has added molybdenum in the alloy, which gives it noticeably better resistance to chlorides compared to 304. For saltwater or salt-air environments, it's the right call over standard stainless. This plug is built from 316, so it's a solid fit for that kind of exposure.
