Product Description: Stock sizes in music wire and stainless steel
All SPEC stock helical extension springs have uniform body diameter and are produced with full twist loops the same diameter as the body. They are wound with initial tension; some force is required before coils are initially separated. As with other Associated Spring stock components, they are capable of wide application for experimental, development, prototype and maintenance work.
Materials
- Music Wire - Per ASTM-A228 or AMS 5112. Music wire springs are not recommended for applications where the temperature exceeds 121 deg. C (250 deg F.)
- Stainless Steel Type 302 - ASTM-A313 or AMS 5688 spring tempered (chemical & physical only). Stainless steel springs are not recommended for applications where the temperature exceeds 260 deg. C (500 deg. F).
- Type 302 stainless steel is slightly magnetic. Surface of stainless steel may have a residue of nickel on the surface. This is normal and will not affect the function of the part.
- Wire diameter is prior to forming.
