Quick answer
Subnautica2Hub, Subnautica2.gg, Dexerto, and Subnautica 2 Wiki describe Metal Salvage as debris from a human habitat or vehicle that is easily converted into raw materials in a Fabricator. Subnautica2Hub lists it as a harvested material used as the ingredient for Salvaged Titanium, requiring one Metal Salvage per craft at the Fabricator. Dexerto Titanium guidance says Metal Salvage near wreck debris can be processed into Salvaged Titanium and yields four Titanium per piece. Subnautica 2 Wiki also lists Metal Salvage as an inventory pickup with buoyancy and mass stats.
Field notes for salvage runs
Pick it up when the route is already paid for
Metal Salvage is best when you are already at a wreck, scanning fragments, or checking old structures. A dedicated salvage trip feels slow; a spare backpack slot on an existing route feels free.
Process it before it becomes clutter
The item is useful because it turns into planned Titanium stock. If it sits in your bag or a random locker for three trips, it is not stock anymore. It is noise.
Use salvage before base expansion
A few processed pieces can cover lockers, hatches, and station placement without draining the loose Titanium pile you need for tools and repairs.
Metal Salvage route plan
Treat wreck debris as a Titanium errand
The item text describes Metal Salvage as human habitat or vehicle debris. When you are already checking wrecks or old structures, leave one or two inventory slots open for salvage.
Do not carry it forever
Subnautica 2 Wiki lists Metal Salvage as an inventory pickup with mass. Bring it home, process it, and free the space before the next resource loop.
Convert through Fabricator
Subnautica2Hub lists Metal Salvage as the ingredient for Salvaged Titanium at the Fabricator. It is a processing step, not a trophy for the locker.
Use it when Titanium demand spikes
Dexerto Titanium guidance reports that Metal Salvage can turn into Salvaged Titanium for four Titanium per piece. That makes it useful before base expansions, storage rows, and tool rebuilds.
Keep salvage separate from loose Titanium
A small salvage box beside the Fabricator keeps the flow obvious: wreck debris in, Titanium stock out. Mixing it with loose resources makes it easier to forget.

Metal Salvage checklist
| Need | What to confirm |
|---|---|
| Source type | Human habitat or vehicle debris. |
| Processing | One Metal Salvage feeds Salvaged Titanium at Fabricator. |
| Titanium value | Dexerto reports four Titanium per processed piece. |
| Inventory | Subnautica 2 Wiki lists pickup, mass, and buoyancy stats. |
| Best timing | Process before base building or locker expansion runs. |
Do not let salvage clog the backpack
Metal Salvage is valuable because it compresses a good Titanium run into one pickup. It stops being valuable when three pieces sit in your bag while you swim past Silver, Quartz, or quest parts.
