Stainless Steel Nitronic 50 Annealed vs Nitronic 50 Cold Drawn

Stainless Steel · Nitronic 50 temper comparison

Nitronic 50 Annealed and Nitronic 50 Cold Drawn are two conditions of the same stainless steel grade, Nitronic 50: Annealed versus Cold Drawn. The chemistry is identical, so every difference below comes from the condition. Nitronic 50 Cold Drawn is the stronger of the two: yield strength 760 MPa (110 ksi) against 430 MPa (62.4 ksi) for Nitronic 50 Annealed, about 77% more; tensile strength follows at 965 MPa (140 ksi) vs 780 MPa (113 ksi). In exchange, Nitronic 50 Annealed is the more ductile: elongation 45% versus 25% for Nitronic 50 Cold Drawn, and Nitronic 50 Cold Drawn is harder (300 HB vs 210 HB). On the shop floor, Nitronic 50 Annealed welds better (very good vs good).
