Stainless Steel 1.4849 vs CF10SMnN
Stainless Steel · grade comparison
Stainless Steel 1.4849 and CF10SMnN are both stainless steel grades. CF10SMnN is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 250 MPa (36.3 ksi) for 1.4849, about 32% more; tensile strength follows at 640 MPa (92.8 ksi) vs 490 MPa (71.1 ksi). CF10SMnN is the more ductile: elongation 42% versus 10% for 1.4849, and CF10SMnN is harder (190 HB vs 180 HB). CF10SMnN is lighter (7.6 g/cm³ vs 7.9 g/cm³ for 1.4849) and CF10SMnN is stiffer (196 GPa vs 170 GPa). On the shop floor, CF10SMnN welds better (very good vs good).

1.4849 vs CF10SMnN: 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.

1.4849 vs CF10SMnN — frequently asked
Is CF10SMnN stronger than 1.4849?
Yes. CF10SMnN has a typical yield strength of 330 MPa (47.9 ksi) against 250 MPa (36.3 ksi) for 1.4849 — about 32% more. Tensile strength is 640 MPa (92.8 ksi) vs 490 MPa (71.1 ksi).
Which is cheaper, 1.4849 or CF10SMnN?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 1.4849 or CF10SMnN?
CF10SMnN, by a small margin. Both rate poor for machinability — 25/100 against 20/100 for 1.4849; for welding the order is CF10SMnN first (very good, 70/100) then 1.4849 (good, 55/100).
