Steel 1075 vs 60SiCr8
Steel · grade comparison
Steel 1075 and 60SiCr8 are both steel grades. 60SiCr8 is the stronger of the two: yield strength 1,550 MPa (225 ksi) against 470 MPa (68.2 ksi) for 1075, about 3.3 times as much; tensile strength follows at 1,750 MPa (254 ksi) vs 830 MPa (120 ksi). In exchange, 1075 is the more ductile: elongation 11% versus 8% for 60SiCr8, and 60SiCr8 is harder (460 HB vs 235 HB). 1075 runs hotter in service (300°C vs 250°C continuous) and 1075 conducts heat better (48 W/m·K vs 30 W/m·K). On the shop floor, 1075 machines more easily (fair vs poor) and 60SiCr8 sits in a lower cost tier (budget, $) than 1075 (standard, $$).
1075Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
60SiCr8Choose it when strength drives the design, or when cost is the deciding factor.
1075 vs 60SiCr8: 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.

1075 vs 60SiCr8 — frequently asked
Is 60SiCr8 stronger than 1075?
Yes. 60SiCr8 has a typical yield strength of 1,550 MPa (225 ksi) against 470 MPa (68.2 ksi) for 1075 — about 3.3 times as much. Tensile strength is 1,750 MPa (254 ksi) vs 830 MPa (120 ksi).
Which is cheaper, 1075 or 60SiCr8?
60SiCr8 is the lower-cost material: it sits in the budget tier ($) while 1075 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, 1075 or 60SiCr8?
1075. Its machinability rates fair (38/100) against poor (15/100) for 60SiCr8; for welding the order is 1075 first (poor, 18/100) then 60SiCr8 (not recommended, 12/100).
