Oil-quenched spring steel wire is an alloy spring steel wire, which is characterized by good fatigue resistance and resistance to elastic decline. It is suitable for making springs such as valve springs that require good fatigue performance and high alternating frequency. After the spring is formed, only tempering is required.
