Storage Requirements for Metal Packing
Briefly introduce the storage requirements for metal packing materials.
Storage Requirements for Metal Packing
Metal fillers (especially carbon steel) are prone to rusting during storage; therefore, proper moisture and rust prevention measures are crucial.
Rust Prevention Treatment
Material | Rust Prevention Measures |
Carbon Steel | Apply rust-preventive oil or phosphate treatment; avoid contact with bare hands (sweat accelerates corrosion) |
Stainless Steel | Keep surface clean; avoid storing with carbon steel |
For long-term storage of carbon steel (>6 months), vacuum packaging with desiccant is recommended.
Storage Environment
Project | Requirements |
Location | Indoor warehouse, no open-air storage |
Humidity | ≤60% (stricter requirements for carbon steel) |
Temperature | -10℃ to 40℃ |
Storage Location | Off the ground, with good ventilation |
Stainless steel and carbon steel should be stored separately and never mixed.
Storage Management
Monthly inspection of packaging for damage and rust.
First-in, first-out (FIFO). Carbon steel should be used within 6 months.
Open-air storage is strictly prohibited. Do not store with acids or alkalis.
Rust Treatment
Situation | Handling |
Slight surface rust on carbon steel | Remove rust with wire brush and solvent cleaning |
Severe corrosion on carbon steel | Pickling or scrapping |
Rust spots on stainless steel | Pickling and passivation treatment |
Summary
Key points for rust prevention of carbon steel fillers: apply oil for sealing, control humidity ≤60%, vacuum packaging for long-term storage. Stainless steel should be used to avoid contamination from carbon steel. Proper storage can effectively prevent rust and ensure performance.
