What's the features of high carbon silicon

Oct 30, 2025

Physical Properties

1. Lower density than steel but higher hardness, combining high strength, high hardness, and high toughness.

2. Superior electrical and thermal conductivity compared to steel, suitable for manufacturing cemented carbide tools, high-speed steel, etc.

3. Melting point approximately 1680℃, stable under high temperature and pressure environments.

 

Chemical Properties

1. Strong oxidation and corrosion resistance, remaining stable even at high temperatures.

2. Excellent deoxidizing properties, reacting rapidly with oxygen in molten steel to improve steel quality.

3. Slag-collecting ability helps filter impurities and purify molten steel.

 

Application Characteristics

1. Can replace traditional ferrosilicon, carburizing agents, etc., reducing steelmaking costs.

2. Suitable for smelting ordinary steel, alloy steel, and special steel, shortening smelting time.

 

Usage Risks

1. Relatively high price; dosage must be controlled to avoid exceeding carbon content limits.

2. Storage and transportation require fire and explosion prevention measures, as these are flammable and explosive materials.
