Stainless Steel 1.4823 vs CD3MCuN
Stainless Steel · grade comparison
Stainless Steel 1.4823 and CD3MCuN are both stainless steel grades. CD3MCuN is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 285 MPa (41.3 ksi) for 1.4823, about 93% more; tensile strength follows at 740 MPa (107 ksi) vs 520 MPa (75.4 ksi). CD3MCuN is the more ductile: elongation 32% versus 6% for 1.4823, and CD3MCuN is harder (230 HB vs 200 HB). 1.4823 runs hotter in service (1,050°C vs 300°C continuous) and CD3MCuN conducts electricity better (2.2 % IACS vs 1.9 % IACS). On the shop floor, CD3MCuN welds better (good vs poor) and 1.4823 sits in a lower cost tier (premium, $$$) than CD3MCuN (high, $$$$).
1.4823Choose it when the part sees heat, or when cost is the deciding factor.
CD3MCuNChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4823 vs CD3MCuN: 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.

1.4823 vs CD3MCuN — frequently asked
Is CD3MCuN stronger than 1.4823?
Yes. CD3MCuN has a typical yield strength of 550 MPa (79.8 ksi) against 285 MPa (41.3 ksi) for 1.4823 — about 93% more. Tensile strength is 740 MPa (107 ksi) vs 520 MPa (75.4 ksi).
Which is cheaper, 1.4823 or CD3MCuN?
1.4823 is the lower-cost material: it sits in the premium tier ($$$) while CD3MCuN is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, 1.4823 or CD3MCuN?
CD3MCuN, by a small margin. Both rate poor for machinability — 30/100 against 22/100 for 1.4823; for welding the order is CD3MCuN first (good, 62/100) then 1.4823 (poor, 25/100).
