High-Carbon Ferro Chrome
Overview & Characteristics
High-Carbon Ferro chrome is a core raw material for stainless steel smelting, with carbon content 4%-10% and chromium content ≥60%. Focusing on "low-cost chromium source + basic deoxidation", it is suitable for rough smelting of 304, 316 and other stainless steels, and a rigid demand product for global stainless steel enterprises.

Production Process
Primarily produced by submerged arc furnace process:
Raw materials: Chrome ore, coke, silica
Process: High-temperature reduction in closed submerged arc furnace
Energy consumption: ≈3000-3500kWh/ton
Modern processes significantly improve energy efficiency and environmental performance through raw material pretreatment and furnace gas recovery.
Product Features
Advantages: Chromium recovery rate ≥80%, fast dissolution in molten steel, cost 40%+ lower than low-carbon ferrochrome;
Compliance: Supports SGS/BV testing, meeting standards of stainless steel mills in Europe, America and Southeast Asia.
Application Scenarios
Stainless steel smelting: Rough smelting of 304/316 stainless steel, providing core chromium element;
Raw material for medium-low carbon ferrochrome: Reducing agent for medium-low carbon ferrochrome production via silicothermic method;
Special steel: Heat-resistant steel, weathering steel, improving corrosion resistance.
FAQ
Q: Main grades and differences?
A: Grades like FeCr55C10.0, FeCr60C8.0 classified by carbon content, numbers indicate Cr content and carbon limit.
Q: How to choose between HC and LC ferrochrome?
A: HC offers better cost efficiency for standard stainless steel; LC is for ultra-low carbon grades at higher cost.
