Blind fastener and manufacturing method therefor
The method for the heat treatment of a blind fastener (1) having a hollow sleeve (3) includes austempering. Austempering includes a step in which the hollow sleeve (3) of cold-rolled low carbon steel with a carbon percentage of 0.08 to 0.13% is heated and maintained from 800°C to 950°C during carbur...

| description | The method for the heat treatment of a blind fastener (1) having a hollow sleeve (3) includes austempering. Austempering includes a step in which the hollow sleeve (3) of cold-rolled low carbon steel with a carbon percentage of 0.08 to 0.13% is heated and maintained from 800°C to 950°C during carburization, and a subsequent step in which isothermal maintenance is performed from 320°C to 500°C. The resulting carbon percentage (CP) value is from 0.3 to 0.5%. Even in the case of a low carbon steel blind fastener, austempering can harden the surface of the sleeve and soften the inner portion other than the surface for suitable deformability in order to provide a blind fastener having a sleeve with high surface hardness and sufficient elongation. |
