Stainless Steel VG-10-ANN vs VG-10-HT60
Stainless Steel · VG-10 temper comparison
VG-10-ANN and VG-10-HT60 are two conditions of the same stainless steel grade, VG-10: ANN (annealed) versus HT60 (hardened & tempered, 60-61 HRC). The chemistry is identical, so every difference below comes from the condition. VG-10-HT60 is the stronger of the two: yield strength 1,850 MPa (268 ksi) against 460 MPa (66.7 ksi) for VG-10-ANN, about 4.0 times as much; tensile strength follows at 2,150 MPa (312 ksi) vs 780 MPa (113 ksi). In exchange, VG-10-ANN is the more ductile: elongation 15% versus 2% for VG-10-HT60, and VG-10-HT60 is harder (61 HRC vs 20 HRC). VG-10-ANN runs hotter in service (400°C vs 180°C continuous). On the shop floor, VG-10-ANN machines more easily (fair vs not recommended).
VG-10-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
VG-10-HT60Choose it when strength drives the design.
VG-10-ANN vs VG-10-HT60: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless 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.

VG-10-ANN vs VG-10-HT60 — frequently asked
Is VG-10-HT60 stronger than VG-10-ANN?
Yes. VG-10-HT60 has a typical yield strength of 1,850 MPa (268 ksi) against 460 MPa (66.7 ksi) for VG-10-ANN — about 4.0 times as much. Tensile strength is 2,150 MPa (312 ksi) vs 780 MPa (113 ksi).
Which condition does FabDigit quote by default, ANN or HT60?
HT60 is the default VG-10 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, VG-10-ANN or VG-10-HT60?
VG-10-ANN. Its machinability rates fair (35/100) against not recommended (12/100) for VG-10-HT60.
