High Carbon Ferrochrome

Introduction

High Carbon Ferrochrome

High Carbon Ferrochrome, commonly known as High Chrome or "Big-Eye Chrome", is easily recognizable by its characteristic circular holes, greenish surface deposits, and honeycomb structure. Some varieties are solid without holes. Compared to silicomanganese alloys and high carbon ferromanganese, its cross-section is rougher with more surface slag.

Common Grades: FeCr55C10 (Domestic Grade). Actual product quality varies and is not limited to national standards.

Specifications: Natural lumps, processed lumps.

Cr Equivalent Basis: 50% Cr basis.

High carbon ferrochrome is categorized by silicon content:

Regular Silicon High Chrome: Si 2.5%–5%
Medium Silicon High Chrome: Si 1.5%–2.5%
Low Silicon High Chrome: Si ≤1.5% (typically ≤1.0%, mostly domestic grade)

Prices vary significantly based on chromium and silicon content: higher chromium and lower silicon lead to higher prices. Low-silicon grades (Si <1.5%) are primarily used for wear-resistant parts. Some steel mills purchase low-titanium high carbon ferrochrome for bearing steel production for optimal cost-effectiveness. Always price based on the agreed Cr equivalent basis.

Applications:

Used as an additive in special steels and alloys to improve the wear resistance and hardness of castings.
High-purity ferrochrome powder is also used in ceramic pigments and other industries.

Packaging & Storage: Supplied in bulk or jumbo bags. The product is moisture-sensitive and must be stored in a dry, well-ventilated environment.
