Steel 16MnCrS5 Annealed vs 16MnCrS5-CR

Steel · 16MnCrS5 temper comparison

16MnCrS5 Annealed and 16MnCrS5-CR are two conditions of the same steel grade, 16MnCrS5: Annealed versus CR (cold rolled). The chemistry is identical, so every difference below comes from the condition. 16MnCrS5-CR is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 350 MPa (50.8 ksi) for 16MnCrS5 Annealed, about 57% more; tensile strength follows at 700 MPa (102 ksi) vs 560 MPa (81.2 ksi). In exchange, 16MnCrS5 Annealed is the more ductile: elongation 25% versus 12% for 16MnCrS5-CR, and 16MnCrS5-CR is harder (210 HB vs 165 HB). 16MnCrS5 Annealed runs hotter in service (180°C vs 150°C continuous).

16MnCrS5 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

16MnCrS5-CRChoose it when strength drives the design.

16MnCrS5 Annealed vs 16MnCrS5-CR — frequently asked

Is 16MnCrS5-CR stronger than 16MnCrS5 Annealed?

Yes. 16MnCrS5-CR has a typical yield strength of 550 MPa (79.8 ksi) against 350 MPa (50.8 ksi) for 16MnCrS5 Annealed — about 57% more. Tensile strength is 700 MPa (102 ksi) vs 560 MPa (81.2 ksi).

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

HR is the default 16MnCrS5 condition in the FabDigit quote flow (neither Annealed nor CR). 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 welds better, 16MnCrS5 Annealed or 16MnCrS5-CR?

16MnCrS5 Annealed. Its weldability rates fair (48/100) against fair (42/100) for 16MnCrS5-CR.
