Stainless Steel 1.4361-C850 vs 1.4361-CD
Stainless Steel · 1.4361 temper comparison
1.4361-C850 and 1.4361-CD are two conditions of the same stainless steel grade, 1.4361: C850 (1/2 Hard) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 1.4361-C850 is the stronger of the two: yield strength 650 MPa (94.3 ksi) against 470 MPa (68.2 ksi) for 1.4361-CD, about 38% more; tensile strength follows at 900 MPa (131 ksi) vs 720 MPa (104 ksi). In exchange, 1.4361-CD is the more ductile: elongation 28% versus 14% for 1.4361-C850, and 1.4361-C850 is harder (275 HB vs 210 HB). 1.4361-CD runs hotter in service (400°C vs 300°C continuous).
1.4361-C850Choose it when strength drives the design.
1.4361-CDChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4361-C850 vs 1.4361-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.

1.4361-C850 vs 1.4361-CD — frequently asked
Is 1.4361-C850 stronger than 1.4361-CD?
Yes. 1.4361-C850 has a typical yield strength of 650 MPa (94.3 ksi) against 470 MPa (68.2 ksi) for 1.4361-CD — about 38% more. Tensile strength is 900 MPa (131 ksi) vs 720 MPa (104 ksi).
Which condition does FabDigit quote by default, C850 or CD?
A is the default 1.4361 condition in the FabDigit quote flow (neither C850 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, 1.4361-C850 or 1.4361-CD?
1.4361-CD, by a small margin. Both rate poor for machinability — 32/100 against 24/100 for 1.4361-C850; for welding the order is 1.4361-CD first (good, 62/100) then 1.4361-C850 (good, 55/100).
