16MnD5 steel introduction and chemical composition

16MnD5 medium carbon quenched and tempered steel has higher strength, toughness and hardenability than 45# steel. It can obtain better comprehensive mechanical properties after quenching and tempering. The cutting performance of 16MnD5 steel is good, but its welding performance is poor, the cold deformation plasticity is low, and has tempering brittleness tendency. 16MnD5 steel is generally used in quenched and tempered state, and it can also be used in normalized state.

16MnD5 steel chemical composition:
Silicon Si: 0.17-0.37, Manganese Mn: 0.70-1.00, Sulfur S:≤0.035, Phosphorus P:≤0.035, Chromium Cr: ≤0.25, Nickel Ni: ≤0.25, Copper Cu: ≤0.25.

16MnD5 steel is used to manufacture worn parts, such as rotating shafts, spindles, crankshafts, spline shafts, connecting rods, universal joint shafts, meshing rods, gears, disks, bolts, nuts, etc.
