Mechanical Properties of GSNb (annealed):
GSNb meets the mechanical properties requirements of ASTM B393 Type 2 Commercial Grade Niobium (UNS R04210)
Tensile Strength	18,000 psi (125 MPa) minimum
Yield Strength	10,500 psi (73 MPa) minimum
Elongation	20 % minimum (above 0.004” thick) 15 % minimum (0.002 to 0.0039” thick)

Additional information not included in ASTM B363 

Hardness (Typical): HV 10
Grain Size (ASTM): 6 or finer (45 ums) for thicknesses < 0.010”

Olsen Cup Testing is available on request for thinner gauges.
GSNb has similar values to Commercial Grade niobium.
Typical Olsen Cup depth values for 0.005 to 0.010” thick GSNb are 0.240” (6.1mm).

Fabrication

Machinability: While challenging, GSNb can be machined using high rake angle tools, slow feeds and speeds, and water-soluble oils.

Weldability: GSNb can be resistance welded to itself and other metals such as tantalum, nickel, platinum, titanium and niobium. It can be welded using GTAW (TIG) using proper shielding and cleanliness techniques. It can also be Electron Beam (EB) welded. 

Heat Treatment: GSNb will recrystallize at temperatures above about 1650 °F (900°C) (Heat treat in vacuum only).

Typical Applications

Sheet/Strip/Foil for forming applications such as crucibles, cups, and formed parts. Any application that can use commercial grade niobium but requires improved forming and surface finish.
