Stainless Steel 1.4749 AS-CAST vs 1.4749-CD
Stainless Steel · 1.4749 temper comparison
1.4749 AS-CAST and 1.4749-CD are two conditions of the same stainless steel grade, 1.4749: AS-CAST versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1.4749-CD is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 250 MPa (36.3 ksi) for 1.4749 AS-CAST, about 100% more; tensile strength follows at 660 MPa (95.7 ksi) vs 450 MPa (65.3 ksi). 1.4749-CD is the more ductile: elongation 14% versus 1.5% for 1.4749 AS-CAST, and 1.4749 AS-CAST is harder (230 HB vs 210 HB). 1.4749-CD is stiffer (200 GPa vs 190 GPa). On the shop floor, 1.4749-CD machines more easily (fair vs poor) and 1.4749-CD welds better (25 vs 15 out of 100).
1.4749-CDChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4749 AS-CAST vs 1.4749-CD: 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.

1.4749 AS-CAST vs 1.4749-CD — frequently asked
Is 1.4749-CD stronger than 1.4749 AS-CAST?
Yes. 1.4749-CD has a typical yield strength of 500 MPa (72.5 ksi) against 250 MPa (36.3 ksi) for 1.4749 AS-CAST — about 100% more. Tensile strength is 660 MPa (95.7 ksi) vs 450 MPa (65.3 ksi).
Which condition does FabDigit quote by default, AS-CAST or CD?
Annealed is the default 1.4749 condition in the FabDigit quote flow (neither AS-CAST nor CD). 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, 1.4749 AS-CAST or 1.4749-CD?
1.4749-CD. Its machinability rates fair (46/100) against poor (28/100) for 1.4749 AS-CAST; for welding the order is 1.4749-CD first (poor, 25/100) then 1.4749 AS-CAST (poor, 15/100).
