Product Introduction
Ferrochrome alloy is an iron alloy primarily composed of chromium and iron, containing 50%-70% chromium. It serves as a core alloy additive in the steelmaking industry. Ferrochrome is classified by carbon content into high-carbon, medium-carbon, low-carbon, and micro-carbon ferrochrome.
Ferrochrome typically appears grayish-white with a glossy, uniform, and dense surface. When an oxide layer forms on the surface, it exhibits a dark gray color.
Ferrochrome has a hardness of 5.5-6.5 and a specific gravity (density) of 4.3-4.8. However, these values may vary depending on the specific composition and manufacturing process of the ferrochrome.

High-Carbon Ferrochrome
Containing 4% to 9% carbon, this is the most widely used type. It is primarily used to manufacture everyday stainless steel kitchenware, stainless steel doors and windows, as well as industrial tool steel and ball bearings.
Medium-Carbon Ferrochrome
Containing 0.5% to 4% carbon, it is finer in texture than high-carbon ferrochrome. It is primarily used to produce standard stainless steel and various mechanical components, such as gears and shaft parts in machinery.
Low-Carbon Ferrochrome
Contains less than 0.5% carbon, offering higher purity. It is suitable for manufacturing high-end stainless steel and heat-resistant steel, such as premium stainless steel thermoses for household use and high-temperature equipment components in industrial settings. It can withstand higher temperatures and is resistant to rust and deformation.
Ultra-low-carbon ferrochrome
Carbon content does not exceed 0.15%. This is the purest form of ferrochrome, primarily used for producing ultra-pure stainless steel and electric heating alloys. Examples include aerospace components and high-end electric heating equipment.
Core Functions of Ferrochrome
① Corrosion and Rust Prevention: Adding ferrochrome to steel creates a dense oxide film on its surface, acting as an invisible protective layer that effectively resists water and air erosion.
② Strength and Hardness Enhancement: Steel treated with ferrochrome exhibits significantly improved strength, hardness, and wear resistance, enabling it to withstand more demanding environments-such as wear-resistant components in industrial machinery and critical automotive parts.
