Nitronic®

Delta Fastener Corp. can provide a wide variety of Nitronic fasteners including; Nitronic nuts, Nitronic bolts, sockets, washers and more Nitronic Fasteners. If we do not have your Nitronic Fasteners in stock (Inch or Metric) we can have these manufactured to your specification.

Material Notes:

Nitronic® stainless steels are austenitic, high-strength, corrosion-resistant products that provide higher-performance alternatives to many conventional 300 and 400 Series stainless steels.

Available in ingot, billet, bar, wire, plate and master melt products, Nitronics® offer approximately twice the strength of 300 Series stainless steels.

Nitronic® alloys provide excellent mechanical properties at both sub-zero and elevated temperatures, impact resistance at low temperatures and, superb resistance to high- temperature oxidation yet retain good weldability and fabricability, and remain non-magnetic even after extensive cold working.

Most common types for fasteners.

NITRONIC® 50 (XM-19) (UNS S20910)

Cr 22, Ni 12.5, Mn 5, Mo 2.25, Si 1 C 0.06 Fe bal.

NITRONIC 60® (Alloy 218) (UNS S21800)
