Steel 60SiCr8 vs 65Mn
Steel · grade comparison
Steel 60SiCr8 and 65Mn are both steel grades. 60SiCr8 is the stronger of the two: yield strength 1,550 MPa (225 ksi) against 440 MPa (63.8 ksi) for 65Mn, about 3.5 times as much; tensile strength follows at 1,750 MPa (254 ksi) vs 760 MPa (110 ksi). In exchange, 65Mn is the more ductile: elongation 16% versus 8% for 60SiCr8, and 60SiCr8 is harder (460 HB vs 215 HB). 65Mn runs hotter in service (350°C vs 250°C continuous) and 65Mn conducts heat better (45 W/m·K vs 30 W/m·K). On the shop floor, 65Mn machines more easily (fair vs poor), 65Mn welds better (poor vs not recommended), and 60SiCr8 sits in a lower cost tier (budget, $) than 65Mn (standard, $$).
60SiCr8Choose it when strength drives the design, or when cost is the deciding factor.
65MnChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
60SiCr8 vs 65Mn: 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.

60SiCr8 vs 65Mn — frequently asked
Is 60SiCr8 stronger than 65Mn?
Yes. 60SiCr8 has a typical yield strength of 1,550 MPa (225 ksi) against 440 MPa (63.8 ksi) for 65Mn — about 3.5 times as much. Tensile strength is 1,750 MPa (254 ksi) vs 760 MPa (110 ksi).
Which is cheaper, 60SiCr8 or 65Mn?
60SiCr8 is the lower-cost material: it sits in the budget tier ($) while 65Mn is standard ($$). 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, 60SiCr8 or 65Mn?
65Mn. Its machinability rates fair (50/100) against poor (15/100) for 60SiCr8; for welding the order is 65Mn first (poor, 25/100) then 60SiCr8 (not recommended, 12/100).
