Nitronic 50

Nitronic 50 is a high strength austenitic stainless steel with good corrosion resistance. Its corrosion resistance is better than that of 317L and its yield strength is approximately double that of 304 and 316 stainless steel. Nitronic 50 does not become magnetic when in sub-zero temperatures or cold worked. This material also has very good mechanical properties/strength at both sub-zero and elevated temperatures.

West Special Fasteners are manufacturers of Nitronic 50 Fasteners.

Nitronic 50 Fasteners such as Socket Setscrews, Socket Countersunk Screws, Bolts, Washers, Nuts, Socket Capscrews, Studbolt, Studs, & machined components to drawings and hot forged items can all be produced at West Special Fasteners Limited.
