Study on ``Strain Tempering (KRK)'' (4th Report). Effects of ``Strain Tempering (KRK)'' on Mechanical Properties of Various Carbon Steel Wires

Jingozaemon Matsuoka


Abstract:

It has been reported that mechanical properties are improved by applying ``Strain Temparing (KRK)'' process to steel wires containing 0.6∼0.9% C. In this paper the effect of carbon content of steel wires on the mechanical properties in this process has been investigated. Results obtained are as follows: (1) In the case of low carbon steel wires, tensile strength, yield strength and hardness are also improved by this process. These improvements in strength and ductility are expected by adopting suitable conditions of this process as in the case of high carbon steel wires (2) The strength increases with carbon content and reduction are increased, but the maximum strengthening is determined by the relation of carbon content, reduction and treating temperature.
