Stainless Steel 1.4002 Annealed vs 1.4002-CD
Stainless Steel · 1.4002 temper comparison
1.4002 Annealed and 1.4002-CD are two conditions of the same stainless steel grade, 1.4002: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1.4002-CD is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 230 MPa (33.4 ksi) for 1.4002 Annealed, about 83% more; tensile strength follows at 560 MPa (81.2 ksi) vs 460 MPa (66.7 ksi). In exchange, 1.4002 Annealed is the more ductile: elongation 26% versus 15% for 1.4002-CD, and 1.4002-CD is harder (185 HB vs 150 HB). 1.4002 Annealed runs hotter in service (700°C vs 450°C continuous).
1.4002 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4002-CDChoose it when strength drives the design.
1.4002 Annealed vs 1.4002-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.

1.4002 Annealed vs 1.4002-CD — frequently asked
Is 1.4002-CD stronger than 1.4002 Annealed?
Yes. 1.4002-CD has a typical yield strength of 420 MPa (60.9 ksi) against 230 MPa (33.4 ksi) for 1.4002 Annealed — about 83% more. Tensile strength is 560 MPa (81.2 ksi) vs 460 MPa (66.7 ksi).
Which condition does FabDigit quote by default, Annealed or CD?
Annealed is the default 1.4002 condition in the FabDigit quote flow. 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, 1.4002 Annealed or 1.4002-CD?
1.4002-CD, by a small margin. Both rate good for machinability — 60/100 against 55/100 for 1.4002 Annealed; for welding the order is 1.4002 Annealed first (very good, 78/100) then 1.4002-CD (very good, 72/100).
