Main Application of High Carbon Ferrochrome
Ferrochrome 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 because chromium is in stainless steel. There is only one element that determines the properties of stainless steel, which is chromium, and each type of stainless steel must contain a certain amount of chromium.
The ferrochromium should be in block shape, and the weight of each piece shall not exceed 15kg, and the weight of the ferrochrome block with a size of less than 20×20mm shall not exceed 5% of the total weight of the ferrochrome. When the buyer has special requirements for the particle size, the supplier and the buyer shall negotiate separately.
There should be no visible non-metallic inclusions on the inside and surface of ferrochrome, but when the coating on the surface of the ingot is not clean, a small amount of it is allowed.
High carbon ferrochromium is mainly used in stainless steel production. The 200 series stainless steel contains about 16% chromium, the 300 series stainless steel contains about 25% chromium, and the 400 series stainless steel contains about 14% chromium. The 300 series stainless steel with high demand for ferrochrome is also a large 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 to cast iron, improve the wear resistance and hardness of cast iron, at the same time make cast iron have good heat resistance; used as a chromium-containing raw material for the production of silicon-chromium alloys and medium, low, and micro-carbon ferrochrome by the slag-free method; used as a chromium-containing raw material for the production of metallic chromium by electrolysis; used for oxygen blowing Method for smelting stainless steel raw materials.
