Steel 50CrVA vs 60Si2Mn
Steel · grade comparison
Steel 50CrVA and 60Si2Mn are both steel grades. 50CrVA is the stronger of the two: yield strength 1,200 MPa (174 ksi) against 480 MPa (69.6 ksi) for 60Si2Mn, about 150% more; tensile strength follows at 1,350 MPa (196 ksi) vs 800 MPa (116 ksi). In exchange, 60Si2Mn is the more ductile: elongation 15% versus 12% for 50CrVA, and 50CrVA is harder (400 HB vs 255 HB). 50CrVA runs hotter in service (250°C vs 200°C continuous). On the shop floor, 60Si2Mn machines more easily (fair vs poor) and 50CrVA sits in a lower cost tier (budget, $) than 60Si2Mn (standard, $$).
50CrVAChoose it when strength drives the design, or when the part sees heat.
60Si2MnChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
50CrVA vs 60Si2Mn: 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.
