Stainless Steel 1.4848 vs CN3MN

Stainless Steel · grade comparison

Stainless Steel 1.4848 and CN3MN are both stainless steel grades. CN3MN is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 280 MPa (40.6 ksi) for 1.4848, about 7% more; tensile strength follows at 620 MPa (89.9 ksi) vs 530 MPa (76.9 ksi). CN3MN is the more ductile: elongation 45% versus 14% for 1.4848, and 1.4848 is harder (190 HB vs 180 HB). 1.4848 is lighter (7.75 g/cm³ vs 8.06 g/cm³ for CN3MN) and CN3MN is stiffer (195 GPa vs 185 GPa). On the shop floor, CN3MN welds better (very good vs fair) and 1.4848 sits in a lower cost tier (premium, $$$) than CN3MN (high, $$$$).
