Stainless Steel S32053-CD vs S32053 CW-1/4H
Stainless Steel · S32053 temper comparison
S32053-CD and S32053 CW-1/4H are two conditions of the same stainless steel grade, S32053: CD (cold drawn) versus CW-1/4H (CW 1/4 Hard). The chemistry is identical, so every difference below comes from the condition. S32053 CW-1/4H is the stronger of the two: yield strength 650 MPa (94.3 ksi) against 600 MPa (87 ksi) for S32053-CD, about 8% more; tensile strength follows at 900 MPa (131 ksi) vs 850 MPa (123 ksi). In exchange, S32053-CD is the more ductile: elongation 25% versus 20% for S32053 CW-1/4H, and S32053 CW-1/4H is harder (285 HB vs 260 HB).

S32053-CD vs S32053 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.

S32053-CD vs S32053 CW-1/4H — frequently asked
Is S32053 CW-1/4H stronger than S32053-CD?
Yes. S32053 CW-1/4H has a typical yield strength of 650 MPa (94.3 ksi) against 600 MPa (87 ksi) for S32053-CD — about 8% more. Tensile strength is 900 MPa (131 ksi) vs 850 MPa (123 ksi).
Which condition does FabDigit quote by default, CD or CW-1/4H?
SA is the default S32053 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, S32053-CD or S32053 CW-1/4H?
S32053-CD, by a small margin. Both rate poor for machinability — 30/100 against 22/100 for S32053 CW-1/4H.
