Confirm the material and mechanical specification before selecting this wire for a piano or spring application.
Spring requirement versus material
The title names high tensile piano spring wire, while the detailed material is low carbon steel. Hot dip galvanizing is also listed, so the proposed wire needs a defined grade and condition.
Diameter choices
Twelve options include 1 mm but not 0.9 mm. The SWG20 reference should be reconciled with a measured diameter rather than treated as proof of an equivalent size.
- Required spring steel grade
- Selected measured diameter
- Delivery and heat treatment state
- Required coating condition
- Mechanical acceptance tests
Evidence before spring use
No measured tensile or fatigue result establishes piano wire performance here. The zinc value lacks an area basis, so confirm coating measurement separately and request evidence that directly addresses the intended spring process.
