Steel 5150-HR vs 5150 Normalized

Steel · 5150 temper comparison

5150-HR and 5150 Normalized are two conditions of the same steel grade, 5150: HR (hot rolled) versus Normalized. The chemistry is identical, so every difference below comes from the condition. 5150 Normalized is the stronger of the two: yield strength 530 MPa (76.9 ksi) against 460 MPa (66.7 ksi) for 5150-HR, about 15% more; tensile strength follows at 870 MPa (126 ksi) vs 800 MPa (116 ksi). 5150 Normalized is the more ductile: elongation 20.7% versus 18% for 5150-HR, and 5150 Normalized is harder (255 HB vs 229 HB).

5150 NormalizedChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

5150-HR vs 5150 Normalized — frequently asked

Is 5150 Normalized stronger than 5150-HR?

Yes. 5150 Normalized has a typical yield strength of 530 MPa (76.9 ksi) against 460 MPa (66.7 ksi) for 5150-HR — about 15% more. Tensile strength is 870 MPa (126 ksi) vs 800 MPa (116 ksi).

Which condition does FabDigit quote by default, HR or Normalized?

HR is the default 5150 condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

When should I choose 5150-HR over 5150 Normalized?

Pick 5150 Normalized when strength drives the design, or when the part is bent, formed or impact-loaded.
