First claim
Opening claim text (preview).
The invention claimed is: 1. An oil tempered wire comprising a steel wire and a lubricant coating disposed around an outer circumference of the steel wire, wherein the lubricant coating includes a lubricant component resin and a binder resin, the lubricant component resin is at least one selected from polyacetals, polyimides, melamine resins and acrylic resins, the deposited mass of the lubricant coating is not less than 1.0 g/m 2 and not more than 4.0 g/m 2 , and the surface roughness Rz of the steel wire is not more than 8.0 μm. 2. The oil tempered wire according to claim 1 , wherein the deposited mass of the lubricant component resin is not less than 0.3 g/m 2 and not more than 3.0 g/m 2 . 3. The oil tempered wire according to claim 1 , wherein the lubricant coating disappears when heated at 400° C. for 20 minutes. 4. The oil tempered wire according to claim 1 , wherein an oxide film is disposed on the surface of the steel wire. 5. The oil tempered wire according to claim 1 , wherein an outer circumference of the lubricant coating is coated with a lubricating oil. 6. The oil tempered wire according to claim 1 , wherein the lubricant component resin is polyacetals. 7. The oil tempered wire according to claim 1 , wherein the lubricant component resin is polyimides. 8. The oil tempered wire according to claim 1 , wherein the lubricant component resin is melamine resins. 9. The oil tempered wire according to claim 1 , wherein the lubricant component resin is acrylic resins.
