Steel 1119 vs 1141

Steel · grade comparison

Steel 1119 and 1141 are both steel grades. 1119 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 360 MPa (52.2 ksi) for 1141, about 15% more. In exchange, 1141 is the more ductile: elongation 22% versus 15% for 1119, and 1141 is harder (192 HB vs 143 HB). On the shop floor, 1119 machines more easily (excellent vs good) and 1119 sits in a lower cost tier (budget, $) than 1141 (standard, $$).

1119Choose it when strength drives the design, or when the part is machined in volume.

1141Choose it when the part is bent, formed or impact-loaded.
