Nitrided ferrochrome vs. Ferrochromium

Nitrided ferrochrome mainly used in smelting of N bearing steels, In Cr-Ni stainless steels, element Ni Can be substituted partly by N.
Ferrochromium is characteristics in its stable N content, high density and high element yield in smelting process.High nitrogen ferrochromium is a new primium alloy additive in steel smelting of super high-strength protective ring steel, valve steel,bearing steel ,etc. It is characterized in its high nitrogen content and low impuries.N yield can be improved as it is in use and the addition can be reduced.

What is Ferro niobium?

Ferro niobium is an important iron niobium alloy, with a niobium content of 60-70%. It is the main source for niobium alloying of HSLA steel and covers more than 80% of the world wide niobium production.
The niobium is mined from pyrochlore deposits and is subsequently transformed into the niobium pentoxide Nb2O5. This oxide is mixed with iron oxide and aluminium and is reduced in the an aluminothermic reaction to niobium and iron.
Ferro Niobium imparts a doubling of strength and toughness as well as weight reduction due to its grain refining attributes in carbon and HSLA steels. The main first use industries for Ferro Niobium are in carbon pipelines, construction and automobiles. It is also added to stainless steel to stop embrittlement after welding.

What are the uses of Zinc chloride?

Zinc chloride (also called soldering flux) is a water-soluble chemical compound. Zinc chloride is the name of chemical compound with the formula ZnCl2 and its hydrates. Zinc chlorides, of which nine crystalline forms are known, are colorless or white, and are highly soluble in water. Zinc chloride finds wide application in textile processing, metallurgical fluxes, and chemical synthesis.
Industrial Applications
Zinc chloride is used in dry cell batteries both as an electrolyte, moisture absorbent and corrosion inhibitor. It is used in fluxes for soldering, galvanizing and tinning. As an excellent emulsion breaker, zinc chloride is used to separate oil from water. It is also used as a packer fluid in oil and gas wells. Zinc chloride is put to use as an inhibitor in potable water treatment plants, cooling towers, and gas and oil wells.
Zinc chloride has the ability to attack metal oxides (MO) to give derivatives of the formula MZnOCl2. This reaction is relevant to the utility of ZnCl2 as a flux for soldering — it dissolves oxide coatings exposing the clean metal surface. Fluxes with ZnCl2 as an active ingredient are sometimes called "Tinner's Fluid". Typically this flux was prepared by dissolving zinc foil in dilute hydrochloric acid until the liquid ceased to evolve hydrogen; for this reason, such flux was once known as killed spirits. Because of its corrosive nature, this flux is not suitable for situations where any residue cannot be cleaned away, such as electronic work. This property also leads to its use in the manufacture of magnesia cements for dental fillings and certain mouthwashes as an active ingredient.

What is Titanium Sponge used for?

Titanium Sponge is a chemical element with the symbol Ti and atomic number 22.
Titanium Sponge can be alloyed with iron, aluminium, vanadium, molybdenum, among other elements, to produce strong lightweight alloys for aerospace (jet engines, missiles, and spacecraft), military, industrial process, automotive, agri-food, medical prostheses, orthopedic implants, dental and endodontic instruments.
Applications
Titanium Sponge is used in steel as an alloying element (ferro-titanium) to reduce grain size and as a deoxidizer, and in stainless steel to reduce carbon content.
Titanium Sponge is an intensely white permanent pigment used in paints, paper, toothpaste, and plastics. It is also used in cement, in gemstones, as an optical opacifier in paper.
Titanium Sponge are used in the chemical and petrochemical industries primarily for corrosion resistance. Specific alloys are used in downhole and nickel hydrometallurgy applications due to their high strength
