The invention discloses a heat treatment process with regard to silicon-manganese alloy spring steel, and belongs to the technical field of heat treatment processes for spring steel. According to the invention, heat treatment steps comprising heating, quenching and tempering can be carried out with regard to the silicon-manganese alloy spring steel, and the heat treatment process is scientific and reasonable in design, and capable of effectively preventing the silicon-manganese alloy spring steel from decarburization and graphitization tendencies; a quenching liquid used in the heat treatment process is safe, environment-friendly and non-toxic, capable of effectively replacing the original oil-based quenching medium with high energy consumption and high pollution, long in service life, and excellent in quenching effect; and in addition, the silicon-manganese alloy spring steel treated through the process is capable of achieving a finished product state, and provided with a layer of anti-rust film, so that add
