Steel S235J2G3-A vs S235J2G3 +N

Steel · S235J2G3 temper comparison

S235J2G3-A and S235J2G3 +N are two conditions of the same steel grade, S235J2G3: A (solution annealed) versus +N (normalized). The chemistry is identical, so every difference below comes from the condition. S235J2G3 +N is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 215 MPa (31.2 ksi) for S235J2G3-A, about 16% more; tensile strength follows at 430 MPa (62.4 ksi) vs 380 MPa (55.1 ksi). In exchange, S235J2G3-A is the more ductile: elongation 31% versus 27% for S235J2G3 +N, and S235J2G3 +N is harder (120 HB vs 108 HB).

S235J2G3-AChoose it when the part is bent, formed or impact-loaded.
