Steel CPM S30V H&T + Cryo 60-61 HRC vs CPM S30V Q&T
Steel · CPM S30V temper comparison
CPM S30V H&T + Cryo 60-61 HRC and CPM S30V Q&T are two conditions of the same steel grade, CPM S30V: H&T + Cryo 60-61 HRC (H&T + Cryogenic treatment) versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. CPM S30V H&T + Cryo 60-61 HRC is the stronger of the two: yield strength 1,950 MPa (283 ksi) against 1,800 MPa (261 ksi) for CPM S30V Q&T, about 8% more; tensile strength follows at 2,200 MPa (319 ksi) vs 2,050 MPa (297 ksi). In exchange, CPM S30V Q&T is the more ductile: elongation 1% versus 0.5% for CPM S30V H&T + Cryo 60-61 HRC, and CPM S30V H&T + Cryo 60-61 HRC is harder (620 HB vs 240 HB). CPM S30V Q&T runs hotter in service (250°C vs 200°C continuous).
CPM S30V H&T + Cryo 60-61 HRCChoose it when strength drives the design.
CPM S30V Q&TChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
CPM S30V H&T + Cryo 60-61 HRC vs CPM S30V 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.

CPM S30V H&T + Cryo 60-61 HRC vs CPM S30V Q&T — frequently asked
Is CPM S30V H&T + Cryo 60-61 HRC stronger than CPM S30V Q&T?
Yes. CPM S30V H&T + Cryo 60-61 HRC has a typical yield strength of 1,950 MPa (283 ksi) against 1,800 MPa (261 ksi) for CPM S30V Q&T — about 8% more. Tensile strength is 2,200 MPa (319 ksi) vs 2,050 MPa (297 ksi).
Which condition does FabDigit quote by default, H&T + Cryo 60-61 HRC or Q&T?
Annealed is the default CPM S30V condition in the FabDigit quote flow (neither H&T + Cryo 60-61 HRC 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 welds better, CPM S30V H&T + Cryo 60-61 HRC or CPM S30V Q&T?
CPM S30V Q&T. Its weldability rates not recommended (10/100) against not recommended (4/100) for CPM S30V H&T + Cryo 60-61 HRC.
