Steel EN19-CR vs EN19 Normalized

Steel · EN19 temper comparison

EN19-CR and EN19 Normalized are two conditions of the same steel grade, EN19: CR (cold rolled) versus Normalized. The chemistry is identical, so every difference below comes from the condition. EN19 Normalized is the stronger of the two: yield strength 655 MPa (95 ksi) against 580 MPa (84.1 ksi) for EN19-CR, about 13% more; tensile strength follows at 1,020 MPa (148 ksi) vs 720 MPa (104 ksi). EN19 Normalized is the more ductile: elongation 17.7% versus 15% for EN19-CR, and EN19 Normalized is harder (302 HB vs 217 HB).

EN19-CR vs EN19 Normalized — frequently asked

Is EN19 Normalized stronger than EN19-CR?

Yes. EN19 Normalized has a typical yield strength of 655 MPa (95 ksi) against 580 MPa (84.1 ksi) for EN19-CR — about 13% more. Tensile strength is 1,020 MPa (148 ksi) vs 720 MPa (104 ksi).

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

HR is the default EN19 condition in the FabDigit quote flow (neither CR nor Normalized). 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.

Which is easier to machine, EN19-CR or EN19 Normalized?

EN19-CR. Its machinability rates good (55/100) against fair (48/100) for EN19 Normalized.
