Steel 1141 vs 1536

Steel · grade comparison

Steel 1141 and 1536 are both steel grades. 1536 is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 360 MPa (52.2 ksi) for 1141, about 53% more. In exchange, 1141 is the more ductile: elongation 22% versus 12% for 1536. On the shop floor, 1141 machines more easily (68 vs 58 out of 100), 1536 welds better (fair vs poor), and 1536 sits in a lower cost tier (budget, $) than 1141 (standard, $$).

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

1536Choose it when strength drives the design, or when it will be welded.
