Stainless Steel 1.4652-CD vs 1.4652 CW-1/4H
Stainless Steel · 1.4652 temper comparison
1.4652-CD and 1.4652 CW-1/4H are two conditions of the same stainless steel grade, 1.4652: CD (cold drawn) versus CW-1/4H (cold worked strip, approx. 1/4 hard). The chemistry is identical, so every difference below comes from the condition. 1.4652 CW-1/4H is the stronger of the two: yield strength 750 MPa (109 ksi) against 700 MPa (102 ksi) for 1.4652-CD, about 7% more; tensile strength follows at 1,000 MPa (145 ksi) vs 950 MPa (138 ksi). In exchange, 1.4652-CD is the more ductile: elongation 25% versus 20% for 1.4652 CW-1/4H, and 1.4652 CW-1/4H is harder (320 HB vs 300 HB). 1.4652-CD runs hotter in service (350°C vs 300°C continuous).
1.4652-CDChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4652 CW-1/4HChoose it when strength drives the design.
1.4652-CD vs 1.4652 CW-1/4H: 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.

1.4652-CD vs 1.4652 CW-1/4H — frequently asked
Is 1.4652 CW-1/4H stronger than 1.4652-CD?
Yes. 1.4652 CW-1/4H has a typical yield strength of 750 MPa (109 ksi) against 700 MPa (102 ksi) for 1.4652-CD — about 7% more. Tensile strength is 1,000 MPa (145 ksi) vs 950 MPa (138 ksi).
Which condition does FabDigit quote by default, CD or CW-1/4H?
Annealed is the default 1.4652 condition in the FabDigit quote flow (neither CD nor CW-1/4H). 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, 1.4652-CD or 1.4652 CW-1/4H?
1.4652-CD. Its machinability rates poor (20/100) against not recommended (12/100) for 1.4652 CW-1/4H.
