Stainless Steel 1.4006 vs 416
Stainless Steel · grade comparison
Stainless Steel 1.4006 and 416 are both stainless steel grades. 1.4006 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 275 MPa (39.9 ksi) for 416, about 9% more. In exchange, 416 is the more ductile: elongation 30% versus 24% for 1.4006. 1.4006 is stiffer (215 GPa vs 200 GPa) and 1.4006 conducts heat better (30 W/m·K vs 24.9 W/m·K). On the shop floor, 416 machines more easily (very good vs fair), 1.4006 welds better (fair vs poor), and 1.4006 sits in a lower cost tier (standard, $$) than 416 (premium, $$$).
1.4006Choose 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.
1.4006 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.

1.4006 vs 416 — frequently asked
Is 1.4006 stronger than 416?
Yes. 1.4006 has a typical yield strength of 300 MPa (43.5 ksi) against 275 MPa (39.9 ksi) for 416 — about 9% more. Tensile strength is 520 MPa (75.4 ksi) vs 515 MPa (74.7 ksi).
Which is cheaper, 1.4006 or 416?
1.4006 is the lower-cost material: it sits in the standard tier ($$) while 416 is premium ($$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, 1.4006 or 416?
416. Its machinability rates very good (80/100) against fair (45/100) for 1.4006; for welding the order is 1.4006 first (fair, 45/100) then 416 (poor, 22/100).
