Stainless Steel 1.4876-CD vs 1.4876-SR
Stainless Steel · 1.4876 temper comparison
1.4876-CD and 1.4876-SR are two conditions of the same stainless steel grade, 1.4876: CD (cold drawn) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. 1.4876-CD is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 450 MPa (65.3 ksi) for 1.4876-SR, about 7% more. In exchange, 1.4876-SR is the more ductile: elongation 28% versus 25% for 1.4876-CD, and 1.4876-CD is harder (200 HB vs 185 HB). 1.4876-SR runs hotter in service (700°C vs 550°C continuous).
1.4876-CDChoose it when strength drives the design.
1.4876-SRChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4876-CD vs 1.4876-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.

1.4876-CD vs 1.4876-SR — frequently asked
Is 1.4876-CD stronger than 1.4876-SR?
Yes. 1.4876-CD has a typical yield strength of 480 MPa (69.6 ksi) against 450 MPa (65.3 ksi) for 1.4876-SR — about 7% more. Tensile strength is 690 MPa (100 ksi) vs 660 MPa (95.7 ksi).
Which condition does FabDigit quote by default, CD or SR?
ANN is the default 1.4876 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 welds better, 1.4876-CD or 1.4876-SR?
1.4876-CD. Its weldability rates very good (80/100) against very good (75/100) for 1.4876-SR.
