TypeAnnealedCarbon Footprint VerificationCompleted
Define actual carbon grade and delivery state when requesting this annealed spring wire coil.
Listed classes and condition
JIS3521 and SW-A, SW-B and SW-C appear in the model field, while the material field is unspecified. Confirm the actual alloy and how annealed condition relates to the requested class.
Size and surface
The only size option is above 0.2 mm, without an upper limit. A round shape and phosphate coating are described, but the exact diameter and coil configuration require agreement.
- Actual carbon designation
- Measured diameter and tolerance
- Annealed or other temper
- Phosphate surface requirements
- Coil and inspection specification
Document verification
No numerical tensile result establishes the stated JIS conformance. Request relevant class and material records, and verify Taiwan origin, ISO and carbon footprint wording separately rather than treat those references as confirmed certification.
