Abstract:  
The invention relates generally to metal working and it has particular relation to machinable steel bars and a method of manufacturing such bars. One object of the present invention is to provide an improved process for manufacturing machinable steel bars such as generally indicated, which requires fewer operations and less time, which results in a superior product uniform and accurate throughout its length, which provides a smooth surface, and which in general involves less expense. Another object of the invention is to provide an improved process such as above indicated which will allow storage of hot rolled bars in a manufacturing plant without removing scale therefrom until immediately before finishing the bars for use in automatic screw machines and the like.
