Columbium Bolts with World Wide Shipping
Columbium / Niobium has physical and chemical properties similar to
those of the element tantalum, and the two are therefore difficult
to distinguish. It is estimated that out of 44,500 metric tons of
niobium mined in 2006, 90% ended up in the production of high-grade
structural steel, followed by its use in superalloys. The use of
niobium alloys for superconductors and in electronic components
account only for a small share of the production
Niobium is an valuable microalloying element for steel. Adding
niobium to the steel causes the formation of niobium carbide and
niobium nitride within the steel. These compounds improve the grain
refining, retardation of recrystallization, and precipitation
hardening of the steel. These effects increase the toughness,
strength, formability, and weldability of the microalloyed steel.
Microalloyed stainless steels have a niobium content of less than
0.1%. It is an important alloy addition to high strength low alloy
steels, which are widely used as structural components in modern
cars. These niobium containing alloys are strong and are often used
in pipeline construction.
Significant amounts of the element, either in its pure form or in
the form of high-purity ferroniobium and nickel niobium, are used in
nickel-, cobalt-, and iron-based superalloys for such applications
as jet engine parts, gas turbines, rocket subassemblies, and heat
resisting and combustion equipment. These superalloys are used, for
example, in advanced air frame systems such as those used in the
NASA rocket program.
Do to their intrinsic properties, Columbium / Niobium alloys are an
excellent material to make hex bolts, nuts, washers, stud bolts, as
well as a large variety of additional fasteners used in corrosive
environments.
