Stainless Steel 410HT Annealed vs 410HT-CD
Stainless Steel · 410HT temper comparison
410HT Annealed and 410HT-CD are two conditions of the same stainless steel grade, 410HT: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 410HT-CD is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 300 MPa (43.5 ksi) for 410HT Annealed, about 83% more; tensile strength follows at 690 MPa (100 ksi) vs 490 MPa (71.1 ksi). In exchange, 410HT Annealed is the more ductile: elongation 25% versus 15% for 410HT-CD, and 410HT-CD is harder (200 HB vs 155 HB). 410HT Annealed runs hotter in service (650°C vs 550°C continuous).
410HT AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
410HT-CDChoose it when strength drives the design.
410HT Annealed vs 410HT-CD: 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.
