Stainless Steel 1.4837 vs CK3MCuN
Stainless Steel · grade comparison
Stainless Steel 1.4837 and CK3MCuN are both stainless steel grades. CK3MCuN is the stronger of the two: yield strength 295 MPa (42.8 ksi) against 265 MPa (38.4 ksi) for 1.4837, about 11% more; tensile strength follows at 585 MPa (84.8 ksi) vs 520 MPa (75.4 ksi). CK3MCuN is the more ductile: elongation 45% versus 12% for 1.4837, and 1.4837 is harder (190 HB vs 175 HB). 1.4837 is lighter (7.7 g/cm³ vs 8 g/cm³ for CK3MCuN) and CK3MCuN is stiffer (195 GPa vs 185 GPa). On the shop floor, CK3MCuN welds better (very good vs fair) and 1.4837 sits in a lower cost tier (premium, $$$) than CK3MCuN (high, $$$$).

CK3MCuNChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
1.4837 vs CK3MCuN: 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.
