| 摘要 |
Provided are a high-strength, high-toughness steel wire rod and a method of manufacturing the same. The steel wire rod of the present invention has a composition including 0.07 wt% to 0.14 wt% of aluminum (Al) and nitrogen (N) wherein Al:N (where Al and N denote wt% of each element) is in a range of 15:1 to 25:1. Since a steel wire rod having sufficient strength and toughness improvement effects can be obtained with a simple alloy component, a steel wire rod capable of allowing processing such as cold forging to be performed without an additional heat treatment may be provided.
