Stainless Steel 1.4017 1/2H vs 1.4017-CD
Stainless Steel · 1.4017 temper comparison
1.4017 1/2H and 1.4017-CD are two conditions of the same stainless steel grade, 1.4017: 1/2H (half hard) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1.4017 1/2H is the stronger of the two: yield strength 600 MPa (87 ksi) against 480 MPa (69.6 ksi) for 1.4017-CD, about 25% more; tensile strength follows at 720 MPa (104 ksi) vs 600 MPa (87 ksi). In exchange, 1.4017-CD is the more ductile: elongation 15% versus 6% for 1.4017 1/2H, and 1.4017 1/2H is harder (238 HB vs 195 HB).
1.4017 1/2HChoose it when strength drives the design.
1.4017-CDChoose it when the part is bent, formed or impact-loaded.
1.4017 1/2H vs 1.4017-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.

1.4017 1/2H vs 1.4017-CD — frequently asked
Is 1.4017 1/2H stronger than 1.4017-CD?
Yes. 1.4017 1/2H has a typical yield strength of 600 MPa (87 ksi) against 480 MPa (69.6 ksi) for 1.4017-CD — about 25% more. Tensile strength is 720 MPa (104 ksi) vs 600 MPa (87 ksi).
Which condition does FabDigit quote by default, 1/2H or CD?
Annealed is the default 1.4017 condition in the FabDigit quote flow (neither 1/2H nor CD). 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, 1.4017 1/2H or 1.4017-CD?
1.4017-CD, by a small margin. Both rate good for machinability — 60/100 against 55/100 for 1.4017 1/2H; for welding the order is 1.4017-CD first (fair, 52/100) then 1.4017 1/2H (fair, 45/100).
