Stainless Steel 1.4501 CAST-5A vs 1.4501-CD
Stainless Steel · 1.4501 temper comparison
1.4501 CAST-5A and 1.4501-CD are two conditions of the same stainless steel grade, 1.4501: CAST-5A versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1.4501-CD is the stronger of the two: yield strength 780 MPa (113 ksi) against 520 MPa (75.4 ksi) for 1.4501 CAST-5A, about 50% more; tensile strength follows at 950 MPa (138 ksi) vs 760 MPa (110 ksi). In exchange, 1.4501 CAST-5A is the more ductile: elongation 28% versus 20% for 1.4501-CD, and 1.4501-CD is harder (310 HB vs 250 HB).
1.4501 CAST-5AChoose it when the part is bent, formed or impact-loaded.
1.4501-CDChoose it when strength drives the design.
1.4501 CAST-5A vs 1.4501-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.

1.4501 CAST-5A vs 1.4501-CD — frequently asked
Is 1.4501-CD stronger than 1.4501 CAST-5A?
Yes. 1.4501-CD has a typical yield strength of 780 MPa (113 ksi) against 520 MPa (75.4 ksi) for 1.4501 CAST-5A — about 50% more. Tensile strength is 950 MPa (138 ksi) vs 760 MPa (110 ksi).
Which condition does FabDigit quote by default, CAST-5A or CD?
SA is the default 1.4501 condition in the FabDigit quote flow (neither CAST-5A 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 welds better, 1.4501 CAST-5A or 1.4501-CD?
1.4501-CD. Its weldability rates good (55/100) against fair (50/100) for 1.4501 CAST-5A.
