What materials are suitable for seawater?
For corrosion resistance, any metal component exposed to seawater should be either brass, bronze, 316 stainless (also known as A4 stainless), titanium, or perhaps aluminum.What is the material selection for seawater valves?
To solve the problem of seawater corrosion, we usually choose titanium, (Super) duplex steel, nickel aluminum bronze, or austenitic stainless steel to manufacture valves, which feature corrosion-resistance and washing-out resistance, ensure service life and longer replacement cycle, and help you save costs and improve Is ss316 suitable for seawater?
The 316 types are used widely in marine applications, but their corrosion resistance in contact with seawater is limited and they cannot be considered 'corrosion proof' under all situations. They are susceptible to localised attack mechanisms, principally crevice and pitting corrosion.- If the fluid handled is seawater, suitable pump material is required: gunmetal or bronze (e. g. multi-alloy aluminium bronze) for the pump casing and impeller and chrome nickel steel for the pump shaft.
