Steel SCM415-CR vs SCM415 Normalized

Steel · SCM415 temper comparison

SCM415-CR and SCM415 Normalized are two conditions of the same steel grade, SCM415: CR (cold rolled) versus Normalized. The chemistry is identical, so every difference below comes from the condition. SCM415-CR is the stronger of the two: yield strength 570 MPa (82.7 ksi) against 440 MPa (63.8 ksi) for SCM415 Normalized, about 30% more; tensile strength follows at 700 MPa (102 ksi) vs 630 MPa (91.4 ksi). In exchange, SCM415 Normalized is the more ductile: elongation 23% versus 14% for SCM415-CR, and SCM415-CR is harder (205 HB vs 180 HB).

SCM415-CRChoose it when strength drives the design.

SCM415 NormalizedChoose it when the part is bent, formed or impact-loaded.
