Steel 1112 vs 1141

Steel · grade comparison

Steel 1112 and 1141 are both steel grades. 1112 is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 360 MPa (52.2 ksi) for 1141, about 31% more. In exchange, 1141 is the more ductile: elongation 22% versus 10% for 1112, and 1141 is harder (192 HB vs 167 HB). On the shop floor, 1112 machines more easily (excellent vs good) and 1112 sits in a lower cost tier (budget, $) than 1141 (standard, $$).

1112Choose 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.
