Steel 20CrMnTi Cold Drawn vs 20CrMnTi Hot Rolled

Steel · 20CrMnTi temper comparison

20CrMnTi Cold Drawn and 20CrMnTi Hot Rolled are two conditions of the same steel grade, 20CrMnTi: Cold Drawn versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. 20CrMnTi Cold Drawn is the stronger of the two: yield strength 650 MPa (94.3 ksi) against 500 MPa (72.5 ksi) for 20CrMnTi Hot Rolled, about 30% more. In exchange, 20CrMnTi Hot Rolled is the more ductile: elongation 16% versus 10% for 20CrMnTi Cold Drawn. 20CrMnTi Hot Rolled runs hotter in service (350°C vs 300°C continuous). On the shop floor, 20CrMnTi Cold Drawn machines more easily (good vs fair).

20CrMnTi Cold DrawnChoose it when strength drives the design, or when the part is machined in volume.

20CrMnTi Hot RolledChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
