Product description
Ferrochromium is an important raw material for the production of stainless steel. It is mainly used in the production of stainless steel, ball bearing steel, tool steel, nitrided steel, heat-strength steel, quenched and tempered steel, carburized steel and hydrogen-resistant steel. This is due to the presence of chromium in stainless steel. There is only one element that determines the properties of stainless steel, which is chromium, and each stainless steel must contain a certain amount of chromium.


Alias
high carbon ferrochrome, also known as big eye chrome


Natural attributes
natural blocks, each block should not exceed 15kg, and the weight of ferrochrome blocks smaller than 20*20mm should not exceed 5% of the total weight of ferrochrome.


Brand
high chromium with 50% chromium content as the benchmark assessment unit.

The main purpose

High-carbon ferrochromium is mainly used in the production of stainless steel, of which 200 series stainless steel contains about 16% chromium, 300 series stainless steel contains about 25% chromium, and 400 series stainless steel contains about 14% chromium. The 300-series stainless steel demanded by ferrochromium is also a proportion of stainless steel production.

Used as an 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; as an additive for cast iron, improve the wear resistance and hardness of cast iron At the same time, the cast iron has good heat resistance; it is used as a chromium-containing raw material for the production of silicon-chromium alloys and medium, low, and micro-carbon ferrochromium by the slag-free method; it is used as a chromium-containing raw material for the production of metal chromium by electrolysis; used for oxygen blowing Raw material for smelting stainless steel.
