Nickel-Niobium Master Alloy
To Specification TY 14-5-67-88
Supplied in lumps of up to 10 kg. The addition of niobium
to stainless and high-temperature steels improves their ductility
and corrosion resistance, increases strength and improves steel weldability.
Niobium is required to make steels and alloys used at high temperatures.
