Stainless Steel 1.4837 vs 1.4874
Stainless Steel · grade comparison
Stainless Steel 1.4837 and 1.4874 are both stainless steel grades. 1.4874 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 265 MPa (38.4 ksi) for 1.4837, about 13% more; tensile strength follows at 560 MPa (81.2 ksi) vs 520 MPa (75.4 ksi). In exchange, 1.4837 is the more ductile: elongation 12% versus 6% for 1.4874, and 1.4874 is harder (225 HB vs 190 HB). On the shop floor, 1.4837 welds better (fair vs poor) and 1.4837 sits in a lower cost tier (premium, $$$) than 1.4874 (high, $$$$).
1.4837Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
1.4874Choose it when strength drives the design.
1.4837 vs 1.4874: 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.
