Steel 60Si2MnA Normalized vs 60Si2MnA Q&T
Steel · 60Si2MnA temper comparison
60Si2MnA Normalized and 60Si2MnA Q&T are two conditions of the same steel grade, 60Si2MnA: Normalized versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 60Si2MnA Q&T is the stronger of the two: yield strength 1,500 MPa (218 ksi) against 650 MPa (94.3 ksi) for 60Si2MnA Normalized, about 131% more; tensile strength follows at 1,700 MPa (247 ksi) vs 1,050 MPa (152 ksi). In exchange, 60Si2MnA Normalized is the more ductile: elongation 10% versus 7% for 60Si2MnA Q&T, and 60Si2MnA Q&T is harder (460 HB vs 300 HB). 60Si2MnA Q&T runs hotter in service (230°C vs 200°C continuous). On the shop floor, 60Si2MnA Normalized machines more easily (34 vs 20 out of 100) and 60Si2MnA Normalized welds better (poor vs not recommended).

60Si2MnA Q&TChoose it when strength drives the design, or when the part sees heat.
60Si2MnA Normalized vs 60Si2MnA 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.

60Si2MnA Normalized vs 60Si2MnA Q&T — frequently asked
Is 60Si2MnA Q&T stronger than 60Si2MnA Normalized?
Yes. 60Si2MnA Q&T has a typical yield strength of 1,500 MPa (218 ksi) against 650 MPa (94.3 ksi) for 60Si2MnA Normalized — about 131% more. Tensile strength is 1,700 MPa (247 ksi) vs 1,050 MPa (152 ksi).
Which condition does FabDigit quote by default, Normalized or Q&T?
Annealed is the default 60Si2MnA 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, 60Si2MnA Normalized or 60Si2MnA Q&T?
60Si2MnA Normalized, by a small margin. Both rate poor for machinability — 34/100 against 20/100 for 60Si2MnA Q&T; for welding the order is 60Si2MnA Normalized first (poor, 22/100) then 60Si2MnA Q&T (not recommended, 10/100).
