Steel 1095 vs 70
Steel · grade comparison
Steel 1095 and 70 are both steel grades. 70 is the stronger of the two: yield strength 1,550 MPa (225 ksi) against 380 MPa (55.1 ksi) for 1095, about 4.1 times as much; tensile strength follows at 1,750 MPa (254 ksi) vs 655 MPa (95 ksi). In exchange, 1095 is the more ductile: elongation 13% versus 6% for 70, and 70 is harder (450 HB vs 192 HB). 1095 runs hotter in service (400°C vs 250°C continuous). On the shop floor, 1095 machines more easily (fair vs poor) and 70 sits in a lower cost tier (budget, $) than 1095 (standard, $$).
1095Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
70Choose it when strength drives the design, or when cost is the deciding factor.
1095 vs 70: 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.
