Steel 20CrMnTi Hot Rolled vs 20CrMnTi Q&T 200C

Steel · 20CrMnTi temper comparison

20CrMnTi Hot Rolled and 20CrMnTi Q&T 200C are two conditions of the same steel grade, 20CrMnTi: Hot Rolled versus Q&T 200C (Q&T). The chemistry is identical, so every difference below comes from the condition. 20CrMnTi Q&T 200C is the stronger of the two: yield strength 930 MPa (135 ksi) against 500 MPa (72.5 ksi) for 20CrMnTi Hot Rolled, about 86% more; tensile strength follows at 1,180 MPa (171 ksi) vs 780 MPa (113 ksi). In exchange, 20CrMnTi Hot Rolled is the more ductile: elongation 16% versus 12% for 20CrMnTi Q&T 200C, and 20CrMnTi Q&T 200C is harder (375 HB vs 225 HB). On the shop floor, 20CrMnTi Hot Rolled machines more easily (fair vs poor) and 20CrMnTi Hot Rolled welds better (fair vs poor).

20CrMnTi Hot Rolled vs 20CrMnTi Q&T 200C — frequently asked

Is 20CrMnTi Q&T 200C stronger than 20CrMnTi Hot Rolled?

Yes. 20CrMnTi Q&T 200C has a typical yield strength of 930 MPa (135 ksi) against 500 MPa (72.5 ksi) for 20CrMnTi Hot Rolled — about 86% more. Tensile strength is 1,180 MPa (171 ksi) vs 780 MPa (113 ksi).

Which condition does FabDigit quote by default, Hot Rolled or Q&T 200C?

Annealed is the default 20CrMnTi condition in the FabDigit quote flow (neither Hot Rolled nor Q&T 200C). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

Which is easier to machine, 20CrMnTi Hot Rolled or 20CrMnTi Q&T 200C?

20CrMnTi Hot Rolled. Its machinability rates fair (48/100) against poor (30/100) for 20CrMnTi Q&T 200C; for welding the order is 20CrMnTi Hot Rolled first (fair, 40/100) then 20CrMnTi Q&T 200C (poor, 20/100).
