  • Nitrogen-containing microalloyed spring steel and preparation method thereof
    Patent number: 11466334
    Abstract: A nitrogen-containing microalloyed spring steel and a preparation method thereof are provided. The chemical components are: 0.45-0.52% of carbon, 0.15-0.35% of silicon, 0.90-1.10% of manganese, 0.90-1.15% of chromium, 0.10-0.25% of molybdenum, 0.10-0.20% of vanadium, 0.025-0.04% of niobium, 0.007-0.012% of nitrogen, less than or equal to 0.03% of lead, tin, zinc, antimony, and bismuth, less than or equal to 25 ppm of oxygen and hydrogen, less than or equal to 0.02% of sulfur and phosphorus, less than or equal to 0.2% of copper, less than or equal to 0.35% nickel, and a balance of iron. The spring steel has significantly improved properties, including high mechanical strength, large elongation, high reduction of area, and good anti-fatigue performance.
