Serving Houston, the United States, and other cities with pride, Louis Metals is a top producer and supplier of Nitronic 30 Bar and Rod products. Nitronic 30 is a nitrogen-strengthened austenitic stainless steel that is well known for its exceptional performance in high-wear and abrasive environments. It was engineered for exceptional strength and corrosion resistance. With their exceptional work-hardening properties and long-term durability, our Nitronic 30 bars and rods are perfect for demanding industrial applications. For industries like mining, transportation, construction, and marine engineering, Louis Metals supplies products that satisfy strict industry standards with an emphasis on quality, accuracy, and customer satisfaction.
About 16–18% chromium, 6–8% manganese, 2–4% nickel, and trace amounts of nitrogen, silicon, and carbon make up Nitronic 30 Bar and Rod. The resistance to corrosion and abrasion is greatly increased by this composition. Nitronic 30 has good impact toughness, excellent elongation (above 35%), and a minimum tensile strength of about 620 MPa and a yield strength of about 275 MPa. It is a good option for heavy-duty and high-stress industrial applications because, in contrast to conventional stainless steels, it offers superior work-hardening rates while retaining excellent weldability and formability.

Common diameters for Nitronic 30 rod typically range from 1/8" to 6", with popular sizes including 1/4", 1/2", 3/4", 1", and 2" for various industrial applications.
Nitronic 30 bars typically come with a smooth finish, although a rough finish may also be available depending on the supplier or the specific processing requirements.
Nitronic 30 rod is typically available in sizes ranging from 1/8" to 3" in diameter. Finishes include hot-rolled, cold-drawn, and polished, offering a smooth, uniform surface for various applications.
Industries that demand high strength, exceptional wear resistance, and corrosion protection frequently use nitronic 30 bars and rods. Transportation vehicles (truck bodies and railcars), mining screens, chutes, conveyors, coal handling equipment and marine parts are examples of common applications. Because of its exceptional formability and weldability, it can be used to create structural components that are exposed to chemicals and mechanical stress. Nitronic 30 is especially useful in settings like wastewater treatment, pulp and paper manufacturing, and bulk material handling where abrasion and corrosion happen at the same time. Its longevity provides long-term, cost-effective performance by lowering the frequency of maintenance and replacement.






We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
