Steel T1 vs W6Mo5Cr4V2
Steel · grade comparison
Steel T1 and W6Mo5Cr4V2 are both steel grades, both tool steel. Both yield at about 560 MPa — strength does not separate them. T1 is the more ductile: elongation 20% versus 12% for W6Mo5Cr4V2. W6Mo5Cr4V2 is lighter (8.16 g/cm³ vs 8.7 g/cm³ for T1) and W6Mo5Cr4V2 runs hotter in service (500°C vs 400°C continuous).
T1Choose it when the part is bent, formed or impact-loaded.
W6Mo5Cr4V2Choose it when weight is the constraint, or when the part sees heat.
T1 vs W6Mo5Cr4V2: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all 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.

T1 vs W6Mo5Cr4V2 — frequently asked
What is the difference between T1 and W6Mo5Cr4V2?
Steel T1 and W6Mo5Cr4V2 are both steel grades, both tool steel. Both yield at about 560 MPa — strength does not separate them. T1 is the more ductile: elongation 20% versus 12% for W6Mo5Cr4V2.
Which is cheaper, T1 or W6Mo5Cr4V2?
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, T1 or W6Mo5Cr4V2?
W6Mo5Cr4V2, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for T1.
