What is Nitronic 33 Bar and Rod?

Nitronic 33 has about 17–19% chromium, 6–9% nickel, with nitrogen additions controlled to enhance strength and corrosion resistance. The yield strength is generally 400–650 MPa, and tensile strength over 800 MPa. It has excellent ductility and impact qualities as well as being non-magnetic in annealed or cold-worked states. The alloy has resistance to atmospheric and chemical corrosion as well as good formability and weldability.
