Stainless Steel Nitronic 50 Cold Drawn vs Nitronic 50 Solution Annealed
Stainless Steel · Nitronic 50 temper comparison
Nitronic 50 Cold Drawn and Nitronic 50 Solution Annealed are two conditions of the same stainless steel grade, Nitronic 50: Cold Drawn versus Solution Annealed. 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 450 MPa (65.3 ksi) for Nitronic 50 Solution Annealed, about 69% more; tensile strength follows at 965 MPa (140 ksi) vs 800 MPa (116 ksi). In exchange, Nitronic 50 Solution Annealed is the more ductile: elongation 45% versus 25% for Nitronic 50 Cold Drawn, and Nitronic 50 Cold Drawn is harder (300 HB vs 217 HB). On the shop floor, Nitronic 50 Solution Annealed welds better (very good vs good).

Nitronic 50 Cold Drawn vs Nitronic 50 Solution Annealed: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
