Stainless Steel CC50 Annealed vs CC50 AS-CAST
Stainless Steel · CC50 temper comparison
CC50 Annealed and CC50 AS-CAST are two conditions of the same stainless steel grade, CC50: Annealed versus AS-CAST. The chemistry is identical, so every difference below comes from the condition. CC50 AS-CAST is the stronger of the two: yield strength 310 MPa (45 ksi) against 275 MPa (39.9 ksi) for CC50 Annealed, about 13% more. In exchange, CC50 Annealed is the more ductile: elongation 10% versus 5% for CC50 AS-CAST, and CC50 AS-CAST is harder (225 HB vs 210 HB).
CC50 AnnealedChoose it when the part is bent, formed or impact-loaded.
CC50 AS-CASTChoose it when strength drives the design.
CC50 Annealed vs CC50 AS-CAST: 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.

CC50 Annealed vs CC50 AS-CAST — frequently asked
Is CC50 AS-CAST stronger than CC50 Annealed?
Yes. CC50 AS-CAST has a typical yield strength of 310 MPa (45 ksi) against 275 MPa (39.9 ksi) for CC50 Annealed — about 13% more. Tensile strength is 500 MPa (72.5 ksi) vs 480 MPa (69.6 ksi).
Which condition does FabDigit quote by default, Annealed or AS-CAST?
Annealed is the default CC50 condition in the FabDigit quote flow. 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, CC50 Annealed or CC50 AS-CAST?
CC50 Annealed. Its machinability rates fair (35/100) against poor (30/100) for CC50 AS-CAST; for welding the order is CC50 Annealed first (poor, 30/100) then CC50 AS-CAST (poor, 25/100).
