Stainless Steel 1.4589 vs 405
Stainless Steel · grade comparison
Stainless Steel 1.4589 and 405 are both stainless steel grades. 1.4589 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 280 MPa (40.6 ksi) for 405, about 7% more. In exchange, 405 is the more ductile: elongation 28% versus 22% for 1.4589, and 1.4589 is harder (170 HB vs 155 HB). 1.4589 is stiffer (220 GPa vs 200 GPa).
1.4589Choose it when strength drives the design.
405Choose it when the part is bent, formed or impact-loaded.
1.4589 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.
