Stainless Steel Nitronic 50 Hot Rolled vs Nitronic 50-HS
Stainless Steel · Nitronic 50 temper comparison
Nitronic 50 Hot Rolled and Nitronic 50-HS are two conditions of the same stainless steel grade, Nitronic 50: Hot Rolled versus HS (high Strength). The chemistry is identical, so every difference below comes from the condition. Nitronic 50-HS is the stronger of the two: yield strength 795 MPa (115 ksi) against 500 MPa (72.5 ksi) for Nitronic 50 Hot Rolled, about 59% more; tensile strength follows at 1,035 MPa (150 ksi) vs 830 MPa (120 ksi). In exchange, Nitronic 50 Hot Rolled is the more ductile: elongation 38% versus 20% for Nitronic 50-HS, and Nitronic 50-HS is harder (320 HB vs 240 HB). On the shop floor, Nitronic 50 Hot Rolled welds better (68 vs 55 out of 100).

Nitronic 50 Hot Rolled vs Nitronic 50-HS: 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.
