What This Sector Is Up Against
Seawater is a stagnant chloride solution with biology in it, and that combination takes apart alloys that pass every laboratory test. The marine programme is built around nickel copper alloys, duplex and super austenitic grades that hold up in flowing and stagnant brine.
Pain Points
- Pitting and crevice failure of stainless shafting and fasteners in seawater
- Stress corrosion cracking on loaded components in brine
- Biofouling in stagnant seawater systems
- Classification society approval requirements on marine material
What Buyers Need
- Nickel copper alloys for seawater pumps, shafts and fasteners
- Duplex plate for cargo tanks and structures where weight matters
- Matched fasteners so the assembly corrodes evenly
- CCS and other classification society documentation

From Enquiry to Container
Step 1
Separate loaded components from simply wetted ones, since that decides Monel 400 against K500
Step 2
Select duplex where weight saving matters and corrosion is chloride driven
Step 3
Match fasteners and fittings to the body grade
Step 4
Issue certificates with classification society documentation where required
Step 5
Pack and ship from Shanghai by FCL, LCL or bulk
