Stainless Steel 08Cr17Ti vs 405
Stainless Steel · grade comparison
Stainless Steel 08Cr17Ti and 405 are both stainless steel grades. 08Cr17Ti is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 280 MPa (40.6 ksi) for 405, about 7% more. 08Cr17Ti runs hotter in service (815°C vs 705°C continuous). On the shop floor, 08Cr17Ti welds better (80 vs 70 out of 100), 08Cr17Ti forms better (very good vs good), and 08Cr17Ti sits in a lower cost tier (standard, $$) than 405 (premium, $$$).

08Cr17Ti 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.

08Cr17Ti vs 405 — frequently asked
Is 08Cr17Ti stronger than 405?
Yes. 08Cr17Ti has a typical yield strength of 300 MPa (43.5 ksi) against 280 MPa (40.6 ksi) for 405 — about 7% more. Tensile strength is 480 MPa (69.6 ksi) vs 480 MPa (69.6 ksi).
Which is cheaper, 08Cr17Ti or 405?
08Cr17Ti is the lower-cost material: it sits in the standard tier ($$) while 405 is premium ($$$). 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, 08Cr17Ti or 405?
405. Its machinability rates good (55/100) against fair (50/100) for 08Cr17Ti; for welding the order is 08Cr17Ti first (very good, 80/100) then 405 (very good, 70/100).
