Reference Standards
Standards and documents buyers should align before quoting 304 round bar
304 round bar buyers often use several naming systems in the same inquiry. Keep the order wording aligned before comparing price.
| Reference | Why Buyers See It | Practical Check |
|---|---|---|
| ASTM A276 | Common stainless steel bar and shape reference | Use it when the order requires ASTM bar wording |
| JIS G4303 / SUS304 | Common Japan-related and Southeast Asia sourcing language | Confirm the PO and MTC use the same naming route |
| MTC / heat number | Batch document for grade, chemistry and traceability | Match the final certificate to 304 or 304L before release |
Reference note: grade-family wording is useful for sourcing, but final acceptance still follows the drawing, PO and current Mill Test Certificate.

| Polished | Cleaner surface | Visible or handling-sensitive parts | Review surface expectation early |
