Steel 35CrMo Normalized vs 35CrMo Q&T

Steel · 35CrMo temper comparison

35CrMo Normalized and 35CrMo Q&T are two conditions of the same steel grade, 35CrMo: Normalized versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 35CrMo Q&T is the stronger of the two: yield strength 880 MPa (128 ksi) against 650 MPa (94.3 ksi) for 35CrMo Normalized, about 35% more. In exchange, 35CrMo Normalized is the more ductile: elongation 18% versus 14% for 35CrMo Q&T, and 35CrMo Q&T is harder (320 HB vs 295 HB). On the shop floor, 35CrMo Normalized welds better (fair vs poor).

35CrMo Normalized vs 35CrMo Q&T — frequently asked

Is 35CrMo Q&T stronger than 35CrMo Normalized?

Yes. 35CrMo Q&T has a typical yield strength of 880 MPa (128 ksi) against 650 MPa (94.3 ksi) for 35CrMo Normalized — about 35% more. Tensile strength is 1,030 MPa (149 ksi) vs 1,000 MPa (145 ksi).

Which condition does FabDigit quote by default, Normalized or Q&T?

HR is the default 35CrMo condition in the FabDigit quote flow (neither Normalized nor Q&T). 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, 35CrMo Normalized or 35CrMo Q&T?

35CrMo Normalized, by a small margin. Both rate fair for machinability — 47/100 against 42/100 for 35CrMo Q&T; for welding the order is 35CrMo Normalized first (fair, 40/100) then 35CrMo Q&T (poor, 30/100).
