In the international context of carbon-neutral and carbon peak policy, the long service life is the main development direction of high-strength and toughness spring steel for major engineering equipment. However, corrosion and hydrogen embrittlement of high-strength spring steel are the bottlenecks that restrict its application in complex service environments. The addition of alloying elements in spring steel can affect the corrosion resistance in many ways, and optimizing and designing the multiple microelements to construct nanoparticles can also have a good effect on hydrogen embrittlement resistance.
