Steel 1141 vs Y30

Steel · grade comparison

Steel 1141 and Y30 are both steel grades. Y30 is the stronger of the two: yield strength 540 MPa (78.3 ksi) against 360 MPa (52.2 ksi) for 1141, about 50% more. In exchange, 1141 is the more ductile: elongation 22% versus 10% for Y30. On the shop floor, Y30 sits in a lower cost tier (budget, $) than 1141 (standard, $$).

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

Y30Choose it when strength drives the design, or when cost is the deciding factor.
