Abstract
Spring steel has excellent elasticity, strength, and toughness. 50CrMnVA spring steel is a high-strength spring steel with excellent mechanical properties and pro-cess performance, so it is widely used in piano tuning pins. This paper investi-gates the effect of quenching temperature on the mechanical properties of 50CrMnVA spring steel, including the microstructure, hardness, and tensile prop-erties of the experimental steel after treatment at different quenching temperatures, and clarifies the effect of aging time on the alloy's microstructure, hardness, strength, elongation, and reduction of area. The results show that the mechanical properties are optimal when the quenching temperature is 860 °C.
