Stainless Steel 405 vs X2CrTi24
Stainless Steel · grade comparison
Stainless Steel 405 and X2CrTi24 are both stainless steel grades. X2CrTi24 is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 280 MPa (40.6 ksi) for 405, about 14% more; tensile strength follows at 520 MPa (75.4 ksi) vs 480 MPa (69.6 ksi). In exchange, 405 is the more ductile: elongation 28% versus 22% for X2CrTi24, and X2CrTi24 is harder (175 HB vs 155 HB). X2CrTi24 is stiffer (220 GPa vs 200 GPa) and X2CrTi24 runs hotter in service (950°C vs 705°C continuous).
405Choose it when the part is bent, formed or impact-loaded.
X2CrTi24Choose it when strength drives the design, or when the part sees heat.
405 vs X2CrTi24: 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.

405 vs X2CrTi24 — frequently asked
Is X2CrTi24 stronger than 405?
Yes. X2CrTi24 has a typical yield strength of 320 MPa (46.4 ksi) against 280 MPa (40.6 ksi) for 405 — about 14% more. Tensile strength is 520 MPa (75.4 ksi) vs 480 MPa (69.6 ksi).
Which is cheaper, 405 or X2CrTi24?
Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 405 or X2CrTi24?
405. Its machinability rates good (55/100) against fair (48/100) for X2CrTi24.
