Analysis of tensile strength influence factors of quenched and tempered spring wire
There are many factors affecting tensile strength of spring wire after quenched and tempered.Both chemical com-position and microstructure have influence on tensile strength of spring wire after quenched and tempered.Complete decar-burization of surface will reduce tensile strength of spring wire after quenched and tempered.Faster heating speed and high-er wire temperature are beneficial to obtain higher tensile strength of spring wire after quenched and tempered.Under the same condition,different quenched medium has different influence on tensile strength of spring wire after quenched and tempered.Tensile strength of spring wire after quenched and tempered can be properly improved by increasing circulating cooling capacity of quenching system.The change of thermocouple insertion depth and tempering temperature will directly affect tensile strength of spring wire after quenched and tempered.
