Stainless Steel 1.4837 vs CK35MN
Stainless Steel · grade comparison
Stainless Steel 1.4837 and CK35MN are both stainless steel grades. 1.4837 is the stronger of the two: yield strength 265 MPa (38.4 ksi) against 250 MPa (36.3 ksi) for CK35MN, about 6% more. In exchange, CK35MN is the more ductile: elongation 30% versus 12% for 1.4837. On the shop floor, 1.4837 sits in a lower cost tier (premium, $$$) than CK35MN (high, $$$$).
1.4837Choose it when strength drives the design, or when cost is the deciding factor.
CK35MNChoose it when the part is bent, formed or impact-loaded.
1.4837 vs CK35MN: 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.
