Stainless Steel Conveyor Belt Material: Choosing and Verifying SUS304 or SUS316
Short answer
Choose SUS304, SUS316 or mild steel from product contact, salt and chemicals, temperature and cleaning. Then make the grade part of the order: confirmed on the drawing, checked against the original for replacements, and documented as required for the order.
01Which grade
| Grade | Typical use |
|---|---|
| SUS304 | Most food lines: freezing, cooling, baking |
| SUS316 | Salt water, brine, stronger cleaning chemicals |
| Mild steel | Dry, hot lines such as ovens and dryers; lightly oiled against rust |
02Checked against the original
For replacement belts, the material of the original belt is checked so the new belt is not a downgrade.
03Grade by material
- ✓Grade written on the confirmed drawing
