Embodiment 1
[0053] This embodiment provides a high-strength spring steel. The weight percentage of each chemical component of the high-strength spring steel is shown in Table 1, wherein the weight percentage of V is controlled to 0.16%.
[0054] In addition, this embodiment also provides the above-mentioned production method of high-strength spring steel. The high-strength spring steel is smelted in a 25kg vacuum induction furnace. The specific steps are as follows:
[0055] S1. Ingredients: According to the weight percentage of each chemical composition of the spring steel of Example 1 in Table 1, prepare raw materials required for smelting, including pure iron, metallic chromium, ferrovanadium, electrolytic manganese, industrial silicon, and graphite blocks.
[0056] S2. Smelting: Put the crucible containing pure iron and 80% graphite block in a 25kg vacuum induction furnace. The order of external silo charging is: industrial silicon, metallic chromium, graphite block, vanadium iron and electro...
