58CrV4
1.8161High-carbon chromium-vanadium spring steel — higher C (0.55-0.62%) than 51CrV4 (0.47-0.55%) for maximum hardness and fatigue strength. V refines grain and improves temper resistance. Used for the most demanding spring applications: heavy-duty coil springs, torsion bars, stabilizer bars, and spring tools. Also used as tool steel (1.2242/59CrV4 variant).
