Steel 1030 vs 1037

Steel · grade comparison

Steel 1030 and 1037 are both steel grades. 1037 is the stronger of the two: yield strength 282 MPa (40.9 ksi) against 260 MPa (37.7 ksi) for 1030, about 8% more; tensile strength follows at 510 MPa (74 ksi) vs 470 MPa (68.2 ksi). 1037 is the more ductile: elongation 26% versus 20% for 1030, and 1037 is harder (79 HRB vs 75 HRB).

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

1030 vs 1037 — frequently asked

Is 1037 stronger than 1030?

Yes. 1037 has a typical yield strength of 282 MPa (40.9 ksi) against 260 MPa (37.7 ksi) for 1030 — about 8% more. Tensile strength is 510 MPa (74 ksi) vs 470 MPa (68.2 ksi).

Which is cheaper, 1030 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 1030 over 1037?

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