Product details

Introduction

5140r steel is one of the most widely used steels in mechanical manufacturing industry. After tempering treatment, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. Good steel hardenability, when water quench hardening to Ф 28 ~ 60 mm, when oil quenching hardening to Ф 15 ~ 40 mm. This kind of steel is suitable for cyanidation and high frequency quenching in addition to tempering treatment. The cutting performance is good, when the hardness is 174 ~ 229HB, the relative machinability is 60%
