Steel 50CrV4 Hot Rolled vs 50CrV4 Q&T
Steel · 50CrV4 temper comparison
50CrV4 Hot Rolled and 50CrV4 Q&T are two conditions of the same steel grade, 50CrV4: Hot Rolled versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 50CrV4 Q&T is the stronger of the two: yield strength 1,050 MPa (152 ksi) against 560 MPa (81.2 ksi) for 50CrV4 Hot Rolled, about 88% more; tensile strength follows at 1,250 MPa (181 ksi) vs 900 MPa (131 ksi). In exchange, 50CrV4 Hot Rolled is the more ductile: elongation 13% versus 10% for 50CrV4 Q&T, and 50CrV4 Q&T is harder (375 HB vs 270 HB). 50CrV4 Q&T runs hotter in service (350°C vs 250°C continuous). On the shop floor, 50CrV4 Hot Rolled machines more easily (48 vs 38 out of 100) and 50CrV4 Hot Rolled welds better (25 vs 15 out of 100).
50CrV4 Hot RolledChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
50CrV4 Q&TChoose it when strength drives the design, or when the part sees heat.
50CrV4 Hot Rolled vs 50CrV4 Q&T: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

50CrV4 Hot Rolled vs 50CrV4 Q&T — frequently asked
Is 50CrV4 Q&T stronger than 50CrV4 Hot Rolled?
Yes. 50CrV4 Q&T has a typical yield strength of 1,050 MPa (152 ksi) against 560 MPa (81.2 ksi) for 50CrV4 Hot Rolled — about 88% more. Tensile strength is 1,250 MPa (181 ksi) vs 900 MPa (131 ksi).
Which condition does FabDigit quote by default, Hot Rolled or Q&T?
Annealed is the default 50CrV4 condition in the FabDigit quote flow (neither Hot Rolled 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, 50CrV4 Hot Rolled or 50CrV4 Q&T?
50CrV4 Hot Rolled, by a small margin. Both rate fair for machinability — 48/100 against 38/100 for 50CrV4 Q&T; for welding the order is 50CrV4 Hot Rolled first (poor, 25/100) then 50CrV4 Q&T (poor, 15/100).
