Stainless Steel S32707-CD vs S32707 HR-SA
Stainless Steel · S32707 temper comparison
S32707-CD and S32707 HR-SA are two conditions of the same stainless steel grade, S32707: CD (cold drawn) versus HR-SA. The chemistry is identical, so every difference below comes from the condition. S32707-CD is the stronger of the two: yield strength 950 MPa (138 ksi) against 780 MPa (113 ksi) for S32707 HR-SA, about 22% more; tensile strength follows at 1,100 MPa (160 ksi) vs 960 MPa (139 ksi). In exchange, S32707 HR-SA is the more ductile: elongation 32% versus 18% for S32707-CD, and S32707-CD is harder (340 HB vs 295 HB).
S32707-CDChoose it when strength drives the design.
S32707 HR-SAChoose it when the part is bent, formed or impact-loaded.
S32707-CD vs S32707 HR-SA: 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.

S32707-CD vs S32707 HR-SA — frequently asked
Is S32707-CD stronger than S32707 HR-SA?
Yes. S32707-CD has a typical yield strength of 950 MPa (138 ksi) against 780 MPa (113 ksi) for S32707 HR-SA — about 22% more. Tensile strength is 1,100 MPa (160 ksi) vs 960 MPa (139 ksi).
Which condition does FabDigit quote by default, CD or HR-SA?
SA is the default S32707 condition in the FabDigit quote flow (neither CD nor HR-SA). 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 welds better, S32707-CD or S32707 HR-SA?
S32707 HR-SA. Its weldability rates good (55/100) against fair (48/100) for S32707-CD.
