Stainless Steel 1.4905 vs 416
Stainless Steel · grade comparison
Stainless Steel 1.4905 and 416 are both stainless steel grades. 1.4905 is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 275 MPa (39.9 ksi) for 416, about 89% more; tensile strength follows at 700 MPa (102 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 is the more ductile: elongation 30% versus 22% for 1.4905, and 1.4905 is harder (220 HB vs 155 HB). 1.4905 is stiffer (218 GPa vs 200 GPa). On the shop floor, 416 machines more easily (very good vs fair), 1.4905 welds better (fair vs poor), and 416 sits in a lower cost tier (premium, $$$) than 1.4905 (high, $$$$).
1.4905Choose it when strength drives the design, or when it will be welded.
416Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
1.4905 vs 416: 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.
