Steel 35CrMo vs 60Si2Mn
Steel · grade comparison
Steel 35CrMo and 60Si2Mn are both steel grades. Both yield at about 490 MPa — strength does not separate them. 35CrMo is the more ductile: elongation 17% versus 15% for 60Si2Mn, and 60Si2Mn is harder (255 HB vs 200 HB). 35CrMo runs hotter in service (480°C vs 200°C continuous). On the shop floor, 35CrMo machines more easily (good vs fair) and 35CrMo welds better (fair vs poor).

35CrMo 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.

35CrMo vs 60Si2Mn — frequently asked
What is the difference between 35CrMo and 60Si2Mn?
Steel 35CrMo and 60Si2Mn are both steel grades. Both yield at about 490 MPa — strength does not separate them. 35CrMo is the more ductile: elongation 17% versus 15% for 60Si2Mn, and 60Si2Mn is harder (255 HB vs 200 HB).
Which is cheaper, 35CrMo or 60Si2Mn?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 35CrMo or 60Si2Mn?
35CrMo. Its machinability rates good (55/100) against fair (45/100) for 60Si2Mn; for welding the order is 35CrMo first (fair, 40/100) then 60Si2Mn (poor, 20/100).
