PATENTING OF STEEL WIRE IN TIN, AND THE STEEL WIRE RESULTING THEREFROM

摘要

A method for patenting carbon steel wire in which cooling is performed by submersing the wire in a molten tin or molten tin alloy bath is presented. As molten tin metal or tin alloys easily wet other metals, care has to be taken to grow an oxide layer on the steel wire prior to cooling. A steel filament cold drawn from a carbon steel wire patented according the method has a surface with traces of tin. The steel filament can be used as a sawing wire or as a filament in a steel cord. The tin metal or tin alloy may replace lead. Lead is known to harm the environment and health.
