Stainless Steel 1.4982-CD vs 1.4982-WW
Stainless Steel · 1.4982 temper comparison
1.4982-CD and 1.4982-WW are two conditions of the same stainless steel grade, 1.4982: CD (cold drawn) versus WW (warm worked (≈15–25 % reduction) bolting condition). The chemistry is identical, so every difference below comes from the condition. 1.4982-CD is the stronger of the two: yield strength 600 MPa (87 ksi) against 560 MPa (81.2 ksi) for 1.4982-WW, about 7% more. In exchange, 1.4982-WW is the more ductile: elongation 25% versus 22% for 1.4982-CD, and 1.4982-WW is harder (252 HV vs 195 HV). On the shop floor, 1.4982-CD machines more easily (fair vs poor) and 1.4982-CD welds better (very good vs good).
1.4982-CDChoose it when strength drives the design, or when the part is machined in volume.
1.4982-WWChoose it when the part is bent, formed or impact-loaded.
1.4982-CD vs 1.4982-WW: 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.

1.4982-CD vs 1.4982-WW — frequently asked
Is 1.4982-CD stronger than 1.4982-WW?
Yes. 1.4982-CD has a typical yield strength of 600 MPa (87 ksi) against 560 MPa (81.2 ksi) for 1.4982-WW — about 7% more. Tensile strength is 800 MPa (116 ksi) vs 780 MPa (113 ksi).
Which condition does FabDigit quote by default, CD or WW?
ST is the default 1.4982 condition in the FabDigit quote flow (neither CD nor WW). 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, 1.4982-CD or 1.4982-WW?
1.4982-CD. Its machinability rates fair (35/100) against poor (24/100) for 1.4982-WW; for welding the order is 1.4982-CD first (very good, 70/100) then 1.4982-WW (good, 55/100).
