Alloy Steel
Alloy Steel feels worth the slot when a real craft, upgrade, or sale plan is already waiting for it after extraction.
Gunpowder is a keep-or-drop material, and it wins the slot only when ammo or explosive crafting is already part of the plan.
Gunpowder matters when the next craft is real, not theoretical. It feels worth carrying when the crew already knows it will turn into ammunition or explosives. If the run still lacks fuel, heals, repairs, or the exact ammo the guns use, those survival stacks do more immediately.
Found through specialized boxes.

Coral Chunk feels useful early because you keep finding places to spend it instead of watching it rot in storage.
Coral Dust starts feeling good the moment you realize it is not random filler and actually feeds ammo people want to craft.
Fabric matters when the next recipe has already moved past scraps, so it wins the slot only if a higher-grade textile input is actually waiting.
Fabric Scraps only deserve cargo space when a live recipe still accepts scraps; otherwise they lose to fuel, heals, and ammo fast.
High-Grade Gunpowder earns cargo space only when a real craft or trade plan already needs it more than the survival stacks competing for the same slot.
Leviathan Meat is the easier Leviathan material to justify, because Food Crates drop it and each stack still sells for 14 Crowns per piece at the pawn shop.
Leviathan Skin is the Leviathan material to route for when your path already hits coral, wreck, or Living Sand Jr POIs and you still want a 14-Crown resource stack on the way out.
It earns a slot when you already know it will become ammunition or explosives instead of sitting in cargo as a maybe-later material.
When no live craft needs it, gunpowder falls behind the supplies that keep weapons firing and the crew alive.
Gunpowder is worth keeping when the next craft already needs it and the slot is not stealing room from more urgent fuel, heals, repairs, or matching ammo.
Gunpowder comes from specialized boxes.
