Steel 1035 vs 28Mn6

Steel · grade comparison

Steel 1035 and 28Mn6 are both steel grades. 28Mn6 is the stronger of the two: yield strength 540 MPa (78.3 ksi) against 320 MPa (46.4 ksi) for 1035, about 69% more; tensile strength follows at 780 MPa (113 ksi) vs 585 MPa (84.8 ksi). In exchange, 1035 is the more ductile: elongation 18% versus 16% for 28Mn6, and 28Mn6 is harder (235 HB vs 163 HB). 1035 conducts heat better (49 W/m·K vs 43 W/m·K). On the shop floor, 1035 welds better (good vs fair).

1035Choose it when the part is bent, formed or impact-loaded, or when it will be welded.

28Mn6Choose it when strength drives the design.

1035 vs 28Mn6 — frequently asked

Is 28Mn6 stronger than 1035?

Yes. 28Mn6 has a typical yield strength of 540 MPa (78.3 ksi) against 320 MPa (46.4 ksi) for 1035 — about 69% more. Tensile strength is 780 MPa (113 ksi) vs 585 MPa (84.8 ksi).

Which is cheaper, 1035 or 28Mn6?

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

Which is easier to machine, 1035 or 28Mn6?

1035, by a small margin. Both rate good for machinability — 60/100 against 55/100 for 28Mn6; for welding the order is 1035 first (good, 55/100) then 28Mn6 (fair, 45/100).
