Ferro Chrome Description
Ferrochrome is an alloy of chromium and iron. Ferrochrome is divided into high carbon ferrochrome, medium carbon ferrochrome, low carbon ferrochrome, and micro carbon ferrochrome depending on its carbon content. Ferrochrome containing sufficient amount of silicon is called silicon chromium alloy. Alloys containing a very small amount of iron and other elements, while the rest are chromium are called chromium metal. Ferrochrome containing a certain amount of nitrogen is called ferrochrome nitride. There is no standard for ferro chrome nitride in China, and the production is customised according to the technical requirements put forward by the user units.

Uses of Micro Carbon Ferro Chrome and Chromium Metal
One of the more valuable properties of chromium is that it improves the oxidation and corrosion resistance of steel by causing the surface of the steel to form, in an oxidising atmosphere, an adherent oxide film.The surface of the steel forms a highly adherent oxide film in an oxidising atmosphere, which then stops oxidising or slows down the rate of oxidation, thus protecting the internal metal. For example: stainless steel containing Cr13% in the atmosphere can resist air oxidation, not easy to rust, and has good toughness and spread. Used in the manufacture of steam turbine blades.
Acid-resistant steel containing Cr 19%, Ni 9% has strong corrosion resistance and high toughness. Made of plate, wire, strip and rolled products used in chemical, petroleum, automobile manufacturing industry and construction industry.
Containing Cr 25%, Ti 1% of heat-resistant steel at high temperatures can maintain the ability to resist oxidation, 1000 ~ 1100 ℃ high temperature does not afford Scale skin, used in the manufacture of aircraft engine valves and so on. Chromium-containing stainless steel in the atomic energy industry has special properties under nuclear radiation, so it occupies a special place in nuclear reactors. Therefore, it occupies a particularly important position in nuclear reactors.
These properties of chromium steel, with the increase of carbon content in steel and significantly reduce the carbon content in these steels are therefore very Low carbon content in these steels is therefore very low, and the ferrochrome added to the steel is also required to have a low carbon content.
Chromium also improves the specific resistance of the alloy, so microcarbon ferrochrome and chromium metal are the raw materials for refining all kinds of electric heating materials.
Some non-ferrous alloys must use chromium metal, which contains very little iron, as a chromium alloying agent.
Ferrochrome nitride can be used to smelt stainless steel, nitrogen is effective in austenogenesis and stabilisation. It refines the grain size of high-chromium steels and improves their machinability. and improves its machinability.
