Stainless Steel 1.4005 vs 416
Stainless Steel · grade comparison
Stainless Steel 1.4005 and 416 are both stainless steel grades. 1.4005 is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 275 MPa (39.9 ksi) for 416, about 16% more; tensile strength follows at 550 MPa (79.8 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 is the more ductile: elongation 30% versus 25% for 1.4005, and 1.4005 is harder (175 HB vs 155 HB). 1.4005 is stiffer (215 GPa vs 200 GPa) and 1.4005 conducts heat better (30 W/m·K vs 24.9 W/m·K). On the shop floor, 1.4005 sits in a lower cost tier (standard, $$) than 416 (premium, $$$).
1.4005Choose it when strength drives the design, or when cost is the deciding factor.
416Choose it when the part is bent, formed or impact-loaded.
1.4005 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.
