Steel 1035 vs 1037

Steel · grade comparison

Steel 1035 and 1037 are both steel grades. 1035 is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 282 MPa (40.9 ksi) for 1037, about 13% more; tensile strength follows at 585 MPa (84.8 ksi) vs 510 MPa (74 ksi). In exchange, 1037 is the more ductile: elongation 26% versus 18% for 1035, and 1035 is harder (163 HB vs 143 HB).

1035Choose it when strength drives the design.

1037Choose it when the part is bent, formed or impact-loaded.

1035 vs 1037 — frequently asked

Is 1035 stronger than 1037?

Yes. 1035 has a typical yield strength of 320 MPa (46.4 ksi) against 282 MPa (40.9 ksi) for 1037 — about 13% more. Tensile strength is 585 MPa (84.8 ksi) vs 510 MPa (74 ksi).

Which is cheaper, 1035 or 1037?

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.

When should I choose 1035 over 1037?

Pick 1035 when strength drives the design. Pick 1037 when the part is bent, formed or impact-loaded.
