Stainless Steel S44536-CD vs S44536-SR
Stainless Steel · S44536 temper comparison
S44536-CD and S44536-SR are two conditions of the same stainless steel grade, S44536: CD (cold drawn) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. S44536-CD is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 330 MPa (47.9 ksi) for S44536-SR, about 52% more; tensile strength follows at 620 MPa (89.9 ksi) vs 500 MPa (72.5 ksi). In exchange, S44536-SR is the more ductile: elongation 25% versus 12% for S44536-CD, and S44536-CD is harder (215 HB vs 173 HB). S44536-SR runs hotter in service (400°C vs 300°C continuous).
S44536-CDChoose it when strength drives the design.
S44536-SRChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
S44536-CD vs S44536-SR: 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.

S44536-CD vs S44536-SR — frequently asked
Is S44536-CD stronger than S44536-SR?
Yes. S44536-CD has a typical yield strength of 500 MPa (72.5 ksi) against 330 MPa (47.9 ksi) for S44536-SR — about 52% more. Tensile strength is 620 MPa (89.9 ksi) vs 500 MPa (72.5 ksi).
Which condition does FabDigit quote by default, CD or SR?
Annealed is the default S44536 condition in the FabDigit quote flow (neither CD nor SR). 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, S44536-CD or S44536-SR?
S44536-CD, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for S44536-SR; for welding the order is S44536-SR first (good, 55/100) then S44536-CD (fair, 50/100).
