Strontium
HarvestMaterialOverview
Refined from Celestine. Radioactive element used in Radioisotope Thermoelectric Generators (or RTGs) and other nuclear applications. Required in 4 crafting recipes: Cavitation Muffler, Strike Armor, Feedback Resonator, and Tadpole Haul Chassis. Its presence in multiple recipes makes it a recurring material demand throughout the early and mid game. As an intermediate material, Strontium represents processed potential — raw resources transformed into something more useful but not yet a final product. Subnautica 2's crafting depth comes from these middle-tier items that require planning to maintain in adequate supply.

How to Obtain
Tips & Strategy
Required for crafting Cavitation Muffler, Strike Armor, Feedback Resonator — gather extra during exploration to avoid dedicated farming trips later.
Store Strontium in a dedicated Wall Locker near your Fabricator — with 4 recipes requiring it, quick access prevents workflow interruption during extended crafting sessions.
Used across multiple crafting stations (Vehicle Crafter, Modification Station) — distribute your Strontium supply between stations or keep it in a central storage area.
Explore different biomes systematically to discover all Strontium sources — harvested organic resources often appear near specific flora or fauna, and identifying these associations makes future gathering predictable.
When gathering Strontium for Cavitation Muffler, also collect Titanium on the same trip — completing all recipe requirements in one expedition saves significant travel time.
