Stainless Steel 410HT Q&T 22-26 HRC vs 410HT Q&T 26-32 HRC
Stainless Steel · 410HT temper comparison
410HT Q&T 22-26 HRC and 410HT Q&T 26-32 HRC are two conditions of the same stainless steel grade, 410HT: Q&T 22-26 HRC (oil/air quenched, tempered ~650–700 °C) versus Q&T 26-32 HRC (quenched and tempered ~590–650 °C). The chemistry is identical, so every difference below comes from the condition. 410HT Q&T 26-32 HRC is the stronger of the two: yield strength 760 MPa (110 ksi) against 585 MPa (84.8 ksi) for 410HT Q&T 22-26 HRC, about 30% more; tensile strength follows at 930 MPa (135 ksi) vs 760 MPa (110 ksi). In exchange, 410HT Q&T 22-26 HRC is the more ductile: elongation 20% versus 16% for 410HT Q&T 26-32 HRC, and 410HT Q&T 26-32 HRC is harder (285 HB vs 240 HB). 410HT Q&T 22-26 HRC runs hotter in service (650°C vs 550°C continuous).
410HT Q&T 22-26 HRCChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
410HT Q&T 26-32 HRCChoose it when strength drives the design.
410HT Q&T 22-26 HRC vs 410HT Q&T 26-32 HRC: 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.

410HT Q&T 22-26 HRC vs 410HT Q&T 26-32 HRC — frequently asked
Is 410HT Q&T 26-32 HRC stronger than 410HT Q&T 22-26 HRC?
Yes. 410HT Q&T 26-32 HRC has a typical yield strength of 760 MPa (110 ksi) against 585 MPa (84.8 ksi) for 410HT Q&T 22-26 HRC — about 30% more. Tensile strength is 930 MPa (135 ksi) vs 760 MPa (110 ksi).
Which condition does FabDigit quote by default, Q&T 22-26 HRC or Q&T 26-32 HRC?
Annealed is the default 410HT condition in the FabDigit quote flow (neither Q&T 22-26 HRC nor Q&T 26-32 HRC). 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, 410HT Q&T 22-26 HRC or 410HT Q&T 26-32 HRC?
410HT Q&T 22-26 HRC, by a small margin. Both rate fair for machinability — 45/100 against 38/100 for 410HT Q&T 26-32 HRC.
