Brian Fasteners, Houston, USA based manufacturers and suppliers, produce and supply Nitronic 30 bars and rods with state-of-the-art forming and finishing operations. Austenitic stainless steel alloy Nitronic 30 has high strength in addition to superior corrosion resistance in oxidizing conditions. Highly detailed dimensional checks and material verification are done on every bar. Supplying chemical processing, food processing, and marine businesses, Brian Fasteners offers specialized sizes, quick shipping, and technical advice. Being a reliable expert, the company guarantees constant availability of Nitronic 30 bars/rods for use in applications requiring corrosion resistance in combination with mechanical strength in industrial applications.
Nitronic 30 is a 20–22% Cr, 9–11% Ni, 5–7% Mn, and 0.1–0.3% N austenitic alloy. Its tensile strength is 800–1,200 MPa, yield strength is 500–900 MPa, and elongation is 30–50%. The alloy has better corrosion resistance against oxidizing acids and sea water and retains strength up to around 600 °C. Work hardening through cold forming also enhances strength. The blend of high mechanical properties and corrosion resistance renders Nitronic 30 as a reliable general-purpose stainless option.
