Steel 1117 vs 1141

Steel · grade comparison

Steel 1117 and 1141 are both steel grades, both machining-friendly steel. 1141 is the stronger of the two: yield strength 360 MPa (52.2 ksi) against 235 MPa (34.1 ksi) for 1117, about 53% more; tensile strength follows at 675 MPa (97.9 ksi) vs 425 MPa (61.6 ksi). In exchange, 1117 is the more ductile: elongation 33% versus 22% for 1141, and 1141 is harder (192 HB vs 121 HB). 1117 conducts electricity better (10.8 % IACS vs 9.5 % IACS). On the shop floor, 1117 welds better (fair vs poor) and 1117 sits in a lower cost tier (budget, $) than 1141 (standard, $$).

1117Choose it when the part is bent, formed or impact-loaded, or when it will be welded.

1141Choose it when strength drives the design.
