Nitronic 50 Alloy Round Bar XM-19 Stainless Steel Bar Nickel Alloy Round Rod Custom Cutting in Length
Overview
XM-19 (also known as Nitronic 50, UNS S20910) round bar is a high-performance austenitic stainless steel product that integrates exceptional corrosion resistance and high strength—attributes unmatched by many commercial alloys in its class. Engineered to outperform conventional grades like 316 and 317, this nickel-alloy round rod delivers reliable performance across extreme temperatures and harsh chemical environments. We offer XM-19 round bars with flexible customization, including diameter options from 5mm to 250mm and custom length cutting to meet precise project requirements.
Chemical Composition (Weight %)
The superior properties of XM-19 round bar stem from its precisely balanced chemical formulation, as specified in industry standards:
| Element | Minimum (%) | Maximum (%) |
|---|---|---|
| Carbon (C) | — | 0.06 |
| Silicon (Si) | — | 1.00 |
| Manganese (Mn) | 4.00 | 6.00 |
| Phosphorus (P) | — | 0.040 |
| Sulfur (S) | — | 0.030 |
| Chromium (Cr) | 20.50 | 23.50 |
| Nickel (Ni) | 11.50 | 13.50 |
| Molybdenum (Mo) | 1.50 | 3.00 |
| Niobium (Nb) | 0.10 | 0.30 |
| Vanadium (V) | 0.10 | 0.30 |
| Nitrogen (N) | 0.20 | 0.40 |
| Iron (Fe) | Balance | Balance |

Mechanical Properties
XM-19 round bar exhibits outstanding mechanical performance in both annealed and cold-worked conditions, with strength levels far exceeding traditional austenitic stainless steels:
| Property | Condition | Value |
|---|---|---|
| Density | 25°C | 7.7–8.03 g/cm³ |
| Elastic Modulus | 25°C | 190–210 GPa |
| Tensile Strength | Annealed | ≥ 690 MPa |
| Tensile Strength | Oil-quenched, tempered at 425°C | 1158 MPa |
| Yield Strength (Rp0.2) | Annealed | ≥ 380 MPa |
| Yield Strength (Rp0.2) | Oil-quenched, tempered at 425°C | 1034 MPa |
| Elongation (A5) | Annealed | ≥ 35% |
| Elongation | Oil-quenched, tempered at 425°C | 15% |
| Brinell Hardness (HB) | Annealed | ≤ 241 |
| Brinell Hardness (HB) | Oil-quenched, tempered at 425°C | 335 |
| Poisson's Ratio | 25°C | 0.27–0.30 |
Notably, the high-strength (HS) variant of XM-19 achieves yield strength 3–4 times that of 316 stainless steel, while maintaining excellent ductility and toughness even at sub-zero temperatures. Additionally, it remains non-magnetic after cold working or low-temperature exposure—an advantage over many austenitic alloys.
