16MnCr5 steel, also designated as SAE 8620, is a high-strength Cr-Mo alloy known for its excellent toughness and workability. Its chemical formula typically includes around 0.16% charcoal, 1.7% manganese, 0.15% silicon, 0.5% Cr, and 0.2% Mo. Consequently, it finds widespread use in applications requiring both strength and the ability to withstand f
