Stainless Steel 1.4980-CD vs 1.4980 CW+A
Stainless Steel · 1.4980 temper comparison
1.4980-CD and 1.4980 CW+A are two conditions of the same stainless steel grade, 1.4980: CD (cold drawn) versus CW+A (cold worked then aged). The chemistry is identical, so every difference below comes from the condition. 1.4980 CW+A is the stronger of the two: yield strength 1,000 MPa (145 ksi) against 690 MPa (100 ksi) for 1.4980-CD, about 45% more; tensile strength follows at 1,240 MPa (180 ksi) vs 900 MPa (131 ksi). In exchange, 1.4980-CD is the more ductile: elongation 20% versus 12% for 1.4980 CW+A, and 1.4980 CW+A is harder (360 HB vs 255 HB). 1.4980 CW+A runs hotter in service (600°C vs 500°C continuous).
1.4980-CDChoose it when the part is bent, formed or impact-loaded.
1.4980 CW+AChoose it when strength drives the design, or when the part sees heat.
1.4980-CD vs 1.4980 CW+A: 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.

1.4980-CD vs 1.4980 CW+A — frequently asked
Is 1.4980 CW+A stronger than 1.4980-CD?
Yes. 1.4980 CW+A has a typical yield strength of 1,000 MPa (145 ksi) against 690 MPa (100 ksi) for 1.4980-CD — about 45% more. Tensile strength is 1,240 MPa (180 ksi) vs 900 MPa (131 ksi).
Which condition does FabDigit quote by default, CD or CW+A?
STA is the default 1.4980 condition in the FabDigit quote flow (neither CD nor CW+A). 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, 1.4980-CD or 1.4980 CW+A?
1.4980-CD, by a small margin. Both rate poor for machinability — 24/100 against 15/100 for 1.4980 CW+A.
