Steel S275J0-CD vs S275J0 +M

Steel · S275J0 temper comparison

S275J0-CD and S275J0 +M are two conditions of the same steel grade, S275J0: CD (cold drawn) versus +M (thermomechanically controlled processed). The chemistry is identical, so every difference below comes from the condition. S275J0-CD is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 315 MPa (45.7 ksi) for S275J0 +M, about 33% more; tensile strength follows at 540 MPa (78.3 ksi) vs 450 MPa (65.3 ksi). In exchange, S275J0 +M is the more ductile: elongation 26% versus 13% for S275J0-CD, and S275J0-CD is harder (170 HB vs 135 HB).

S275J0-CDChoose it when strength drives the design.

S275J0 +MChoose it when the part is bent, formed or impact-loaded.
