Nitronic 50 Round Bar
Nitronic 50 Round Bar Manufacturer & Supplier
Emirerri Steel is a trusted manufacturer and supplier of Nitronic 50 Round Bar, known for their exceptional strength, corrosion resistance, and toughness. Nitronic 50, also referred to as XM-19 or UNS S20910, is an austenitic stainless steel that provides nearly twice the yield strength of conventional 300 series stainless steels.
These round bars exhibit superior resistance to pitting, crevice corrosion, and stress corrosion cracking — making them ideal for use in demanding marine, chemical, and industrial environments.
Key Features
High Strength: Offers nearly double the yield strength of 316/316L stainless steel.- Excellent Corrosion Resistance: Performs exceptionally in marine and chemical environments.
- Non-Magnetic in Annealed Condition: Retains non-magnetic properties even when cold worked.
- Superior Weldability and Formability: Can be easily fabricated and welded without post-weld heat treatment.
- Low Magnetic Permeability: Suitable for applications where magnetism is a concern.
- Oxidation Resistance: Performs well at elevated temperatures up to 1200°F (649°C).
