Stainless Steel 1.4369 Annealed vs 1.4369-CD
Stainless Steel · 1.4369 temper comparison
1.4369 Annealed and 1.4369-CD are two conditions of the same stainless steel grade, 1.4369: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1.4369-CD is the stronger of the two: yield strength 700 MPa (102 ksi) against 400 MPa (58 ksi) for 1.4369 Annealed, about 75% more; tensile strength follows at 950 MPa (138 ksi) vs 750 MPa (109 ksi). In exchange, 1.4369 Annealed is the more ductile: elongation 48% versus 18% for 1.4369-CD, and 1.4369-CD is harder (290 HB vs 210 HB). 1.4369 Annealed runs hotter in service (800°C vs 400°C continuous).
1.4369 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4369-CDChoose it when strength drives the design.
1.4369 Annealed vs 1.4369-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.
