Stainless Steel 1.4864-CD vs 1.4864-HR
Stainless Steel · 1.4864 temper comparison
1.4864-CD and 1.4864-HR are two conditions of the same stainless steel grade, 1.4864: CD (cold drawn) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. 1.4864-CD is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 245 MPa (35.5 ksi) for 1.4864-HR, about 84% more; tensile strength follows at 700 MPa (102 ksi) vs 570 MPa (82.7 ksi). In exchange, 1.4864-HR is the more ductile: elongation 42% versus 28% for 1.4864-CD, and 1.4864-CD is harder (200 HB vs 155 HB).
1.4864-CDChoose it when strength drives the design.
1.4864-HRChoose it when the part is bent, formed or impact-loaded.
1.4864-CD vs 1.4864-HR: 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.

1.4864-CD vs 1.4864-HR — frequently asked
Is 1.4864-CD stronger than 1.4864-HR?
Yes. 1.4864-CD has a typical yield strength of 450 MPa (65.3 ksi) against 245 MPa (35.5 ksi) for 1.4864-HR — about 84% more. Tensile strength is 700 MPa (102 ksi) vs 570 MPa (82.7 ksi).
Which condition does FabDigit quote by default, CD or HR?
ANN is the default 1.4864 condition in the FabDigit quote flow (neither CD nor HR). 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, 1.4864-CD or 1.4864-HR?
1.4864-CD, by a small margin. Both rate poor for machinability — 33/100 against 27/100 for 1.4864-HR; for welding the order is 1.4864-HR first (very good, 70/100) then 1.4864-CD (good, 65/100).
