16MnCr5 steel, also designated as SAE 8620, is a high-strength Cr-Mo alloy known for its excellent ductility and tempering. Its chemical composition typically includes around 0.16% carbon, 1.7% manganese content, 0.15% silicon, 0.5% chromium content, and 0.2% Mo. Consequently, it finds widespread use in applications requiring both strength and the
