1.4487 vs CE8MN — frequently asked

Is CE8MN stronger than 1.4487?

Yes. CE8MN has a typical yield strength of 500 MPa (72.5 ksi) against 250 MPa (36.3 ksi) for 1.4487 — about 100% more. Tensile strength is 720 MPa (104 ksi) vs 530 MPa (76.9 ksi).

Which is cheaper, 1.4487 or CE8MN?

Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, 1.4487 or CE8MN?

1.4487. Its machinability rates fair (40/100) against poor (32/100) for CE8MN; for welding the order is 1.4487 first (excellent, 90/100) then CE8MN (good, 65/100).
