Stainless Steel 1.4565-CD vs 1.4565 WT-SA
Stainless Steel · 1.4565 temper comparison
1.4565-CD and 1.4565 WT-SA are two conditions of the same stainless steel grade, 1.4565: CD (cold drawn) versus WT-SA (welded Tube, Solution Annealed). The chemistry is identical, so every difference below comes from the condition. 1.4565-CD is the stronger of the two: yield strength 700 MPa (102 ksi) against 440 MPa (63.8 ksi) for 1.4565 WT-SA, about 59% more; tensile strength follows at 950 MPa (138 ksi) vs 820 MPa (119 ksi). In exchange, 1.4565 WT-SA is the more ductile: elongation 45% versus 30% for 1.4565-CD, and 1.4565-CD is harder (280 HB vs 210 HB). 1.4565 WT-SA runs hotter in service (450°C vs 300°C continuous).
1.4565-CDChoose it when strength drives the design.
1.4565 WT-SAChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4565-CD vs 1.4565 WT-SA: 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.

1.4565-CD vs 1.4565 WT-SA — frequently asked
Is 1.4565-CD stronger than 1.4565 WT-SA?
Yes. 1.4565-CD has a typical yield strength of 700 MPa (102 ksi) against 440 MPa (63.8 ksi) for 1.4565 WT-SA — about 59% more. Tensile strength is 950 MPa (138 ksi) vs 820 MPa (119 ksi).
Which condition does FabDigit quote by default, CD or WT-SA?
SA is the default 1.4565 condition in the FabDigit quote flow (neither CD nor WT-SA). 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, 1.4565-CD or 1.4565 WT-SA?
1.4565 WT-SA. Its weldability rates good (65/100) against good (60/100) for 1.4565-CD.
