Process for hardening Feiten and similar tools.
The subject of the invention is a method for hardening files and similar tools, namely the essence of the invention is that the objects to be hardened in a powder (hardening agent) of the composition below are annealed in a known manner in the absence of air, whereby the same one Maintain the cemented surface, but remain supple and flexible, which is very important when it comes to files.
The composition of the hardener is as follows:
EMI1.1
<tb>
<tb> leather powder <SEP>. <SEP>. <SEP>. <SEP>. <SEP>. <SEP>. <SEP>. <SEP>. <SEP>. <SEP>. <SEP>. <SEP>. <SEP>. <SEP>. <SEP>. <SEP>. <SEP>. <SEP> 60 <SEP> parts
