Steel 1141 vs 1212
Steel · grade comparison
Steel 1141 and 1212 are both steel grades, both machining-friendly steel. 1141 is the stronger of the two: yield strength 360 MPa (52.2 ksi) against 220 MPa (31.9 ksi) for 1212, about 64% more; tensile strength follows at 675 MPa (97.9 ksi) vs 386 MPa (56 ksi). In exchange, 1212 is the more ductile: elongation 28% versus 22% for 1141, and 1141 is harder (192 HB vs 121 HB). 1212 conducts electricity better (10.8 % IACS vs 9.5 % IACS). On the shop floor, 1212 machines more easily (excellent vs good) and 1212 sits in a lower cost tier (budget, $) than 1141 (standard, $$).
1141Choose it when strength drives the design.
1212Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
1141 vs 1212: 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.
