Stainless Steel S82013-CD vs S82013 HF-SA
Stainless Steel · S82013 temper comparison
S82013-CD and S82013 HF-SA are two conditions of the same stainless steel grade, S82013: CD (cold drawn) versus HF-SA (hot Finished + Solution Annealed Bar). The chemistry is identical, so every difference below comes from the condition. S82013-CD is the stronger of the two: yield strength 720 MPa (104 ksi) against 520 MPa (75.4 ksi) for S82013 HF-SA, about 38% more; tensile strength follows at 880 MPa (128 ksi) vs 720 MPa (104 ksi). In exchange, S82013 HF-SA is the more ductile: elongation 30% versus 18% for S82013-CD, and S82013-CD is harder (285 HB vs 225 HB). S82013 HF-SA runs hotter in service (280°C vs 250°C continuous). On the shop floor, S82013 HF-SA welds better (65 vs 55 out of 100).

S82013-CD vs S82013 HF-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.

S82013-CD vs S82013 HF-SA — frequently asked
Is S82013-CD stronger than S82013 HF-SA?
Yes. S82013-CD has a typical yield strength of 720 MPa (104 ksi) against 520 MPa (75.4 ksi) for S82013 HF-SA — about 38% more. Tensile strength is 880 MPa (128 ksi) vs 720 MPa (104 ksi).
Which condition does FabDigit quote by default, CD or HF-SA?
SA is the default S82013 condition in the FabDigit quote flow (neither CD nor HF-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, S82013-CD or S82013 HF-SA?
S82013 HF-SA. Its weldability rates good (65/100) against good (55/100) for S82013-CD.
