RFQ: NAB Aluminium Bronze Ball Valve Class 150
When BOQs say aluminium bronze or NAB — not SS316 — for seawater shutoff.
Why this page exists (6 similar lines in our RFQ archive)
Marine and desal RFQs specify NAB/Al-bronze explicitly; SS316 is often rejected for seawater.

Frequently asked questions
C95800 or C95500?
C95800 (NAB) is the usual seawater grade; match the BOQ UNS number.
Why not SS316 in seawater?
Pitting/crevice risk in chlorides — NAB or duplex/super duplex preferred.
