Stainless Steel S82011 1/4H vs S82011-CD
Stainless Steel · S82011 temper comparison
S82011 1/4H and S82011-CD are two conditions of the same stainless steel grade, S82011: 1/4H (quarter hard) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. S82011 1/4H is the stronger of the two: yield strength 750 MPa (109 ksi) against 700 MPa (102 ksi) for S82011-CD, about 7% more. In exchange, S82011-CD is the more ductile: elongation 18% versus 12% for S82011 1/4H, and S82011 1/4H is harder (290 HB vs 270 HB).
S82011 1/4HChoose it when strength drives the design.
S82011-CDChoose it when the part is bent, formed or impact-loaded.
S82011 1/4H vs S82011-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.

S82011 1/4H vs S82011-CD — frequently asked
Is S82011 1/4H stronger than S82011-CD?
Yes. S82011 1/4H has a typical yield strength of 750 MPa (109 ksi) against 700 MPa (102 ksi) for S82011-CD — about 7% more. Tensile strength is 900 MPa (131 ksi) vs 860 MPa (125 ksi).
Which condition does FabDigit quote by default, 1/4H or CD?
Annealed is the default S82011 condition in the FabDigit quote flow (neither 1/4H 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.
When should I choose S82011 1/4H over S82011-CD?
Pick S82011 1/4H when strength drives the design. Pick S82011-CD when the part is bent, formed or impact-loaded.
