Stainless Steel 15Cr25Ti vs 430
Stainless Steel · grade comparison
Stainless Steel 15Cr25Ti and 430 are both stainless steel grades. Both yield at about 300 MPa — strength does not separate them. 430 is the more ductile: elongation 30% versus 22% for 15Cr25Ti, and 15Cr25Ti is harder (180 HB vs 155 HB). 15Cr25Ti runs hotter in service (1,050°C vs 815°C continuous) and 430 conducts heat better (26 W/m·K vs 21 W/m·K). On the shop floor, 430 welds better (good vs fair) and 430 sits in a lower cost tier (standard, $$) than 15Cr25Ti (premium, $$$).
15Cr25TiChoose it when the part sees heat.
430Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
15Cr25Ti vs 430: 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.

15Cr25Ti vs 430 — frequently asked
What is the difference between 15Cr25Ti and 430?
Stainless Steel 15Cr25Ti and 430 are both stainless steel grades. Both yield at about 300 MPa — strength does not separate them. 430 is the more ductile: elongation 30% versus 22% for 15Cr25Ti, and 15Cr25Ti is harder (180 HB vs 155 HB).
Which is cheaper, 15Cr25Ti or 430?
430 is the lower-cost material: it sits in the standard tier ($$) while 15Cr25Ti is premium ($$$). 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, 15Cr25Ti or 430?
430, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for 15Cr25Ti; for welding the order is 430 first (good, 60/100) then 15Cr25Ti (fair, 40/100).
