Stainless Steel 1.4980-CD vs 1.4980 STA-900
Stainless Steel · 1.4980 temper comparison
1.4980-CD and 1.4980 STA-900 are two conditions of the same stainless steel grade, 1.4980: CD (cold drawn) versus STA-900 (solution treated 900 °C + aged 720 °C/16 h). The chemistry is identical, so every difference below comes from the condition. 1.4980 STA-900 is the stronger of the two: yield strength 760 MPa (110 ksi) against 690 MPa (100 ksi) for 1.4980-CD, about 10% more; tensile strength follows at 1,035 MPa (150 ksi) vs 900 MPa (131 ksi). 1.4980 STA-900 is harder — 320 HB against 255 HB for 1.4980-CD — which matters for wear surfaces and threads. 1.4980 STA-900 runs hotter in service (650°C vs 500°C continuous). On the shop floor, 1.4980-CD forms better (fair vs poor).
1.4980 STA-900Choose it when strength drives the design, or when surface hardness matters.
1.4980-CD vs 1.4980 STA-900: 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 STA-900 — frequently asked
Is 1.4980 STA-900 stronger than 1.4980-CD?
Yes. 1.4980 STA-900 has a typical yield strength of 760 MPa (110 ksi) against 690 MPa (100 ksi) for 1.4980-CD — about 10% more. Tensile strength is 1,035 MPa (150 ksi) vs 900 MPa (131 ksi).
Which condition does FabDigit quote by default, CD or STA-900?
STA is the default 1.4980 condition in the FabDigit quote flow (neither CD nor STA-900). 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 STA-900?
1.4980-CD, by a small margin. Both rate poor for machinability — 24/100 against 18/100 for 1.4980 STA-900.
