Spring Steel Flat Wire ASTM A228 Music Wire from United States
Spring steel flat wire, made from oil-tempered alloy steel per ASTM A228, is drawn into a flat rectangular cross-section for use in springs and clips. The wire's high tensile strength comes from its alloy composition and tempering process. It is classified as other alloy steel wire, as it does not meet the definitions of specialty steels in Chapter 72.
