Questions about Galvanized Steel Wire
- When springs were heat treated, it caused discoloration of galvanizing.
- See “Causes of Discoloration of Springs Using Galvanized Steel Wire” for details.
- Do you use hexavalent chromium in galvanizing?
- We do not perform chrome treatment using hexavalent chromium or trivalent chromium.
See “Environmental Properties of Galvanized Steel Wire” for details. - Are there environmental documents, such as RoHS, REACH, SGS Report, and SDS available?
- You can download PDF from “Environmental Information.”
- What is the best heat treatment temperature?
- The recommended heat treatment temperature is less than 240℃.
See “Optimum Heat Treatment Temperature for Galvanized Steel Wire” for details. - How can I store products after they are unpacked?
- Be sure to tightly seal and store the unused wire.
See “Storage Precautions for Galvanized Steel Wire” for details.
Questions about Copper plated Steel Wire
