Stainless Steel S30V H&T + Cryo vs S30V Hardened & Tempered
Stainless Steel · S30V temper comparison
S30V H&T + Cryo and S30V Hardened & Tempered are two conditions of the same stainless steel grade, S30V: H&T + Cryo (H&T + cryogenic treatment) versus Hardened & Tempered (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. S30V H&T + Cryo is the stronger of the two: yield strength 1,980 MPa (287 ksi) against 1,800 MPa (261 ksi) for S30V Hardened & Tempered, about 10% more; tensile strength follows at 2,230 MPa (323 ksi) vs 1,950 MPa (283 ksi). S30V H&T + Cryo is the more ductile: elongation 1.5% versus 1% for S30V Hardened & Tempered, and S30V H&T + Cryo is harder (660 HB vs 255 HB). S30V Hardened & Tempered runs hotter in service (300°C vs 200°C continuous).
S30V H&T + CryoChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
S30V Hardened & TemperedChoose it when the part sees heat.
S30V H&T + Cryo vs S30V Hardened & Tempered: 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.

S30V H&T + Cryo vs S30V Hardened & Tempered — frequently asked
Is S30V H&T + Cryo stronger than S30V Hardened & Tempered?
Yes. S30V H&T + Cryo has a typical yield strength of 1,980 MPa (287 ksi) against 1,800 MPa (261 ksi) for S30V Hardened & Tempered — about 10% more. Tensile strength is 2,230 MPa (323 ksi) vs 1,950 MPa (283 ksi).
Which condition does FabDigit quote by default, H&T + Cryo or Hardened & Tempered?
Annealed is the default S30V condition in the FabDigit quote flow (neither H&T + Cryo 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.
Which welds better, S30V H&T + Cryo or S30V Hardened & Tempered?
S30V Hardened & Tempered. Its weldability rates not recommended (10/100) against not recommended (3/100) for S30V H&T + Cryo.
