Steel CPM 10V H&T 62-64 HRC vs CPM 10V Hardened & Tempered
Steel · CPM 10V temper comparison
CPM 10V H&T 62-64 HRC and CPM 10V Hardened & Tempered are two conditions of the same steel grade, CPM 10V: H&T 62-64 HRC (high austenitising (~1150–1175 °C) + triple temper 540 °C) versus Hardened & Tempered (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. CPM 10V H&T 62-64 HRC is the stronger of the two: yield strength 1,950 MPa (283 ksi) against 1,750 MPa (254 ksi) for CPM 10V Hardened & Tempered, about 11% more. CPM 10V H&T 62-64 HRC is harder — 690 HB against 650 HB for CPM 10V Hardened & Tempered — which matters for wear surfaces and threads.
CPM 10V H&T 62-64 HRCChoose it when strength drives the design, or when surface hardness matters.
CPM 10V H&T 62-64 HRC vs CPM 10V Hardened & Tempered: 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 10V H&T 62-64 HRC vs CPM 10V Hardened & Tempered — frequently asked
Is CPM 10V H&T 62-64 HRC stronger than CPM 10V Hardened & Tempered?
Yes. CPM 10V H&T 62-64 HRC has a typical yield strength of 1,950 MPa (283 ksi) against 1,750 MPa (254 ksi) for CPM 10V Hardened & Tempered — about 11% more. Tensile strength is 2,100 MPa (305 ksi) vs 2,000 MPa (290 ksi).
Which condition does FabDigit quote by default, H&T 62-64 HRC or Hardened & Tempered?
Annealed is the default CPM 10V condition in the FabDigit quote flow (neither H&T 62-64 HRC nor Hardened & Tempered). 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.
When should I choose CPM 10V H&T 62-64 HRC over CPM 10V Hardened & Tempered?
Pick CPM 10V H&T 62-64 HRC when strength drives the design, or when surface hardness matters.
