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.

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.
Product Standards & Specifications
Our XM-19 round bars comply with global industry standards to ensure consistency and reliability:

Key Applications
XM-19 round bar is the material of choice for industries requiring both corrosion resistance and high strength. Its versatility makes it suitable for:
Oil & Gas/Petrochemical: Downhole rigging, pump shafts, valves, and fittings—outperforming 316 and 17-4 PH in sour environments
Marine Engineering: Marine hardware, boat shafts, chains, and fasteners—resisting saltwater corrosion with double the yield strength of 316
Chemical Processing: Heat exchanger components, reactor parts, and piping for handling aggressive chemicals
Nuclear Industry: Nuclear fuel recycling equipment and structural components
Additional Sectors: Pulp and paper mills, textile machinery, medical equipment, and high-strength springs
Customization & Value-Added Services
We understand that every project has unique needs, so we offer comprehensive customization:
Precision Cutting: Custom length cutting to your exact specifications (no minimum order for cutting services)
Surface Finishes: Cold-drawn (mill finish), centerless ground, and polished options
Packaging: Standard seaworthy packaging or custom packaging for international shipping
Lead Time: 7–21 days, with sample availability for quality verification
Supply Capacity: Up to 10,000 tons per month to support large-scale projects
Why Choose Our XM-19 Round Bar?
