LTS-20681 galvanized high-carbon flat spring wire has five actual dimension-pair choices. The1000–2800MPa tensile reference requires actual grade and supplied-condition evidence.
Select an actual flat section
Actual pairs are1x3,4x1,5x1.5,6x2 and2x0.6mm. The4x1.2mm parameter differs from actual4x1mm,while2.5x1mm is not an actual choice.
- Flat wire is the type.
- Five dimension pairs are selectable.
- Galvanized surface is described.
- ±0.01mm tolerance is stated.
- Custom sizes are referenced.
Confirm section orientation and tests
1x3 versus3x1 wording needs drawing orientation clarified. Request actual dimensions,tolerance basis and tensile test scope.
Define tent-spring acceptance
Tent/foldable-spring use does not establish fatigue life or a completed design. Obtain actual grade,treatment and coating records before selecting the wire for repeated bending.
