• The influence of Cr content on the microstructure and properties of spring steel 60Si2CrVA (treated with quenching–tempering and quenching–partitioning–tempering (QPT) processes) was studied. Heat treatment parameters were optimized, and the appropriate Cr content was determined. Optimal microstructure and mechanical properties of 60Si2CrVA steel were obtained at 1.45 wt% Cr or 1.55 wt% Cr. Q–P–T treatment with its strength–toughness combinations is beneficial for 60Si2CrVA spring steel. •The integrated effect of alloy element and heat treatment was explored.•Bauschinger torsion experiments were performed to test elastic sag resistance.•Integrated mechanical properties of spring steel with Q–P–T process are superior.
