Steel 1330-HR vs 1330 Normalized

Steel · 1330 temper comparison

1330-HR and 1330 Normalized are two conditions of the same steel grade, 1330: HR (hot rolled) versus Normalized. The chemistry is identical, so every difference below comes from the condition. 1330 Normalized is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 415 MPa (60.2 ksi) for 1330-HR, about 35% more; tensile strength follows at 835 MPa (121 ksi) vs 690 MPa (100 ksi). 1330 Normalized is harder — 248 HB against 197 HB for 1330-HR — which matters for wear surfaces and threads. On the shop floor, 1330-HR forms better (45 vs 35 out of 100).

1330-HR vs 1330 Normalized — frequently asked

Is 1330 Normalized stronger than 1330-HR?

Yes. 1330 Normalized has a typical yield strength of 560 MPa (81.2 ksi) against 415 MPa (60.2 ksi) for 1330-HR — about 35% more. Tensile strength is 835 MPa (121 ksi) vs 690 MPa (100 ksi).

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

HR is the default 1330 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 1330-HR over 1330 Normalized?

Pick 1330 Normalized when strength drives the design, or when surface hardness matters.
