FERRO ALLOY LUMPS
During the steel making it used as cleanser of impurities some time metallurgist call it scavenger of liquid steel. It Improves both strength and corrosion resistance while limiting austenite grain size. At 0.25-0.60 percent titanium content, carbon combines with the titanium, allowing chromium to remain at grain boundaries and resist oxidization.
It is normaly used as alloying or additive during the steel manufacturing. Molybdenum 0.2-5%, in stainless steels, increases hardenability and strength, particular at high temperatures. Often used in chromium-nickel austenitic steels, molybdenum protects against pitting corrosion caused by chlorides and sulphur chemicals
Manganese used as de-oxidising agent during the steel making and as a alloying agent. Addition of 0.25-13% of Mn, Increases strength at high temperatures by eliminating the formation of iron sulfides. Manganese also improves hardenability, ductility and wear resistance. Like nickel, manganese is an austenite forming element and can be used in the AISI 200 Series of Austenitic stainless steels as a substitute for nickel.
Ferro Vanadium is an alloy which is formed by combining iron and vanadium . Ferro Vanadium is a universal hardener, strengthener and anti-corrosive additive for steels like high-strength low-alloy (HSLA) steel, tool steels, as well as other ferrous-based products.
Ferro Vanadium, as an additive to the production process of ferrous metals, will impart several desirable properties upon the resulting new compound.
One of the primary benefits of adding Ferro Vanadium to an alloy is its stability against alkalis as well as sulphuric and hydrochloric acids. Additionally, the adding of Ferro Vanadium to an alloy can result in a steel product less susceptible to corrosion of any type. Ferro Vanadium is also used to reduce weight while simultaneously increasing the tensile strength of the material.
