Stainless Steel 1.4607 vs 405
Stainless Steel · grade comparison
Stainless Steel 1.4607 and 405 are both stainless steel grades. 1.4607 is the stronger of the two: yield strength 310 MPa (45 ksi) against 280 MPa (40.6 ksi) for 405, about 11% more. 1.4607 is harder — 165 HB against 155 HB for 405 — which matters for wear surfaces and threads. 1.4607 is stiffer (220 GPa vs 200 GPa) and 1.4607 runs hotter in service (950°C vs 705°C continuous). On the shop floor, 405 machines more easily (good vs fair), 1.4607 welds better (excellent vs very good), and 1.4607 sits in a lower cost tier (standard, $$) than 405 (premium, $$$).
1.4607Choose it when strength drives the design, or when surface hardness matters.
405Choose it when the part is machined in volume.
1.4607 vs 405: 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.
