Stainless Steel S82122-CD vs S82122 CW 1/4H
Stainless Steel · S82122 temper comparison
S82122-CD and S82122 CW 1/4H are two conditions of the same stainless steel grade, S82122: CD (cold drawn) versus CW 1/4H (cold worked strip/tube, quarter-hard temper). The chemistry is identical, so every difference below comes from the condition. S82122 CW 1/4H is the stronger of the two: yield strength 750 MPa (109 ksi) against 700 MPa (102 ksi) for S82122-CD, about 7% more. In exchange, S82122-CD is the more ductile: elongation 18% versus 12% for S82122 CW 1/4H, and S82122 CW 1/4H is harder (300 HB vs 285 HB). S82122-CD runs hotter in service (300°C vs 250°C continuous).
S82122-CDChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
S82122 CW 1/4HChoose it when strength drives the design.
S82122-CD vs S82122 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.

S82122-CD vs S82122 CW 1/4H — frequently asked
Is S82122 CW 1/4H stronger than S82122-CD?
Yes. S82122 CW 1/4H has a typical yield strength of 750 MPa (109 ksi) against 700 MPa (102 ksi) for S82122-CD — about 7% more. Tensile strength is 900 MPa (131 ksi) vs 860 MPa (125 ksi).
Which condition does FabDigit quote by default, CD or CW 1/4H?
Annealed is the default S82122 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, S82122-CD or S82122 CW 1/4H?
S82122-CD. Its machinability rates fair (36/100) against poor (27/100) for S82122 CW 1/4H.
