Steel T1 vs W6Mo5Cr4V3
Steel · grade comparison
Steel T1 and W6Mo5Cr4V3 are both steel grades. Both yield at about 560 MPa — strength does not separate them. T1 is the more ductile: elongation 20% versus 12% for W6Mo5Cr4V3, and W6Mo5Cr4V3 is harder (248 HB vs 235 HB). W6Mo5Cr4V3 is lighter (8.05 g/cm³ vs 8.7 g/cm³ for T1) and T1 runs hotter in service (400°C vs 300°C continuous).
T1Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
W6Mo5Cr4V3Choose it when weight is the constraint.
T1 vs W6Mo5Cr4V3: 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 W6Mo5Cr4V3 — frequently asked
What is the difference between T1 and W6Mo5Cr4V3?
Steel T1 and W6Mo5Cr4V3 are both steel grades. Both yield at about 560 MPa — strength does not separate them. T1 is the more ductile: elongation 20% versus 12% for W6Mo5Cr4V3, and W6Mo5Cr4V3 is harder (248 HB vs 235 HB).
Which is cheaper, T1 or W6Mo5Cr4V3?
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 W6Mo5Cr4V3?
T1. Its machinability rates fair (35/100) against poor (30/100) for W6Mo5Cr4V3.
