ASP 2030 vs Böhler S390 — frequently asked

Is Böhler S390 stronger than ASP 2030?

Yes. Böhler S390 has a typical yield strength of 700 MPa (102 ksi) against 600 MPa (87 ksi) for ASP 2030 — about 17% more. Tensile strength is 1,000 MPa (145 ksi) vs 950 MPa (138 ksi).

Which is cheaper, ASP 2030 or Böhler S390?

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

When should I choose ASP 2030 over Böhler S390?

Pick ASP 2030 when the part is bent, formed or impact-loaded. Pick Böhler S390 when strength drives the design, or when the part sees heat.
