Main applications of low carbon ferrochrome

Ferrochrome is the important material in the manufacture of the stainless steel, mainly applied in the production of stainless steel, bearing steel, tool steel, nitriding steel, refractory steel, quenched and tempered steel, carburized steel and hydrogen resistant steel, this is due to the difference of chromium in stainless steel, decided to properties of stainless steel is only one element, and this is chrome, each kind of stainless steel must contain a certain amount of chromium.

The ferrochrome should be block shape, each weight should not be more than 15kg, size less than 20×20mm ferrochrome block weight does not exceed 5% of the total weight of ferrochrome.If the buyer has special requirements for particle size, the buyer and the buyer shall negotiate separately.

No non-metallic inclusions visible to the naked eye can be found inside or on the surface of ferrochrome, but a small amount is allowed when the paint on the surface of the ingot is not clean.

Low carbon Ferro chrome is mainly used in the production of stainless steel, 200 series stainless steel chromium content is about 16%, 300 series stainless steel chromium content is about 25%, 400 series stainless steel chromium content is about 14%.Ferrochrome large demand for 300 series of stainless steel is also a large proportion of stainless steel production products.

Used as alloying agent for ball steel, tool steel and high speed steel with high carbon content, to improve the hardenability of steel, increase the wear resistance and hardness of steel;Used as an additive for cast iron, improve the wear resistance and hardness of cast iron, and make cast iron have good heat resistance;Used as chromium-containing raw material for producing Si-Cr alloy and medium, low and micro carbon ferrochrome by slag-free method;Used as raw material containing chromium in electrolysis production of metal chromium;Used as raw material for smelting stainless steel by oxygen blowing.
