Steel 60Si2MnA Annealed vs 60Si2MnA Q&T
Steel · 60Si2MnA temper comparison
60Si2MnA Annealed and 60Si2MnA Q&T are two conditions of the same steel grade, 60Si2MnA: Annealed 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 550 MPa (79.8 ksi) for 60Si2MnA Annealed, about 173% more; tensile strength follows at 1,700 MPa (247 ksi) vs 900 MPa (131 ksi). In exchange, 60Si2MnA Annealed is the more ductile: elongation 14% versus 7% for 60Si2MnA Q&T, and 60Si2MnA Q&T is harder (460 HB vs 260 HB). 60Si2MnA Q&T runs hotter in service (230°C vs 200°C continuous). On the shop floor, 60Si2MnA Annealed machines more easily (fair vs poor) and 60Si2MnA Annealed welds better (poor vs not recommended).
60Si2MnA AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
60Si2MnA Q&TChoose it when strength drives the design, or when the part sees heat.
60Si2MnA Annealed 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 Annealed vs 60Si2MnA Q&T — frequently asked
Is 60Si2MnA Q&T stronger than 60Si2MnA Annealed?
Yes. 60Si2MnA Q&T has a typical yield strength of 1,500 MPa (218 ksi) against 550 MPa (79.8 ksi) for 60Si2MnA Annealed — about 173% more. Tensile strength is 1,700 MPa (247 ksi) vs 900 MPa (131 ksi).
Which condition does FabDigit quote by default, Annealed or Q&T?
Annealed is the default 60Si2MnA condition in the FabDigit quote flow. 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 Annealed or 60Si2MnA Q&T?
60Si2MnA Annealed. Its machinability rates fair (45/100) against poor (20/100) for 60Si2MnA Q&T; for welding the order is 60Si2MnA Annealed first (poor, 25/100) then 60Si2MnA Q&T (not recommended, 10/100).
