16MnCr5 steel, also designated as SAE 8620, is a robust chromium-molybdenum alloy known for its excellent toughness and hardenability. Its chemical make-up typically includes around 0.16% charcoal, 1.7% manganese content, 0.15% Si, 0.5% chromium content, and 0.2% Mo. Consequently, it finds widespread use in applications requiring both strength and
