Stainless Steel Nitronic 50 Annealed vs Nitronic 50 Hot Rolled
Stainless Steel · Nitronic 50 temper comparison
Nitronic 50 Annealed and Nitronic 50 Hot Rolled are two conditions of the same stainless steel grade, Nitronic 50: Annealed versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. Nitronic 50 Hot Rolled is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 430 MPa (62.4 ksi) for Nitronic 50 Annealed, about 16% more; tensile strength follows at 830 MPa (120 ksi) vs 780 MPa (113 ksi). In exchange, Nitronic 50 Annealed is the more ductile: elongation 45% versus 38% for Nitronic 50 Hot Rolled, and Nitronic 50 Hot Rolled is harder (240 HB vs 210 HB).
Nitronic 50 AnnealedChoose it when the part is bent, formed or impact-loaded.
Nitronic 50 Hot RolledChoose it when strength drives the design.
Nitronic 50 Annealed vs Nitronic 50 Hot Rolled: 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.

Nitronic 50 Annealed vs Nitronic 50 Hot Rolled — frequently asked
Is Nitronic 50 Hot Rolled stronger than Nitronic 50 Annealed?
Yes. Nitronic 50 Hot Rolled has a typical yield strength of 500 MPa (72.5 ksi) against 430 MPa (62.4 ksi) for Nitronic 50 Annealed — about 16% more. Tensile strength is 830 MPa (120 ksi) vs 780 MPa (113 ksi).
Which condition does FabDigit quote by default, Annealed or Hot Rolled?
Solution Annealed is the default Nitronic 50 condition in the FabDigit quote flow (neither Annealed nor Hot Rolled). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
When should I choose Nitronic 50 Annealed over Nitronic 50 Hot Rolled?
Pick Nitronic 50 Annealed when the part is bent, formed or impact-loaded. Pick Nitronic 50 Hot Rolled when strength drives the design.
