Dia 2.9 Niobium Wire 


Among
the various microalloyed elements of steel, scrap niobium is the most
effective microalloying element, and the effect of niobium is so great
that the iron atom contains abundant niobium atoms to achieve the
purpose of improving the properties of the steel. In fact, adding 0.001% -0.1% niobium to the steel is sufficient to change the mechanical properties of the steel. For
example: when adding 0.1% alloying elements, improve the yield strength
of steel were: niobium 118MPa; vanadium 71.5MPa; molybdenum 40MPa;
manganese 17.6MPa; titanium is zero. In fact, only 0.03% -0.05% Nb is added to the steel and the yield strength of the steel can be increased by more than 30%. The cost of steel only increased by 1 US dollars per ton. For example: ordinary medium-carbon steel yield strength is generally
250MPa, adding a small amount of niobium can increase the strength to
350-800MPa. 
Niobium
as a micro-alloying element added to the steel does not change the
structure of iron, but with the steel carbon # nitrogen # sulfur,
changing the microstructure of steel. The
strengthening effect of niobium on steel is mainly fine grain
strengthening and dispersion strengthening, and niobium can form stable
carbides and carbonitrides in the steel with carbon and nitrogen. It is also possible to disperse the carbide and form a steel with fine crystallinity. 
Niobium can also be precipitated by inducing precipitation and control the cooling rate, to achieve diffusion of precipitates. Adjust the toughness of the steel over a wide range. Therefore,
the addition of niobium can not only improve the strength of steel, but
also can improve the toughness of steel, high temperature oxidation and
corrosion resistance! Reduce the brittle transition temperature of
steel to obtain good weldability and formability This component is
widely used in coiled tubing In the pipe material.
