NOBLE ALLOYS
When added to crude steel, ferrovanadium creates a product that is lightweight and extremely high in tensile strength and wear resistance.
The largest practical application of Ferro Vanadium is in the alloying process of any hardened steel.
When a large amount is added with chromium and tungsten in steel, to make high speed tools noted for hardness retention over a moderate temperature range. Vanadium steels are used in high – pressure boilers, locomotive parts, gears and turbines.

It is used in steelmaking as a cleaning agent for iron and steel. The titanium is highly reactive to sulfur, carbon, oxygen, and nitrogen. It is used for deoxidizing and sometimes for desulfurization and denitrification.
Titanium is used in gray iron. A small percentage promotes Graphitization. It is highly reactive in steel making and combines readily, and forms stable compounds with carbon, oxygen, nitrogen & sulphur. Because of its reactivity, it may be used to fix these elements, reducing eliminating their sometimes harmful effects.

Ferro Niobium has anti-corrosive properties (better than carbon steel). The adding of Ferro Niobium to an alloy can make it more weldable and much stronger. The largest practical application of Ferro Niobium is in the alloying process of HSLA steel.

Ferromolybdenum is the alloy of molybdenum and iron. It is often used as an introducer for molybdenum element during steel-making.
While molybdenum may frequently be used interchangeably with chromium and vanadium When added to steel, steel will be given a close-grained structure and higher hardenability, which are in favor of get rid of temper brittleness. In high-speed steel, molybdenum can be used to partially replace tungsten.
Cast iron with molybdenum will have a higher strength and wear resistance, corrosion resistance.
