3. Key Characteristics & Applications

• Characteristics:

  • High Efficiency: Large surface area enables rapid dissolution and high, consistent chromium yield.

  • Precise Composition: Facilitates accurate chemical control.

  • Application Flexibility: Morphology and particle size can be customized for different processes.

• Applications:

  • Stainless Steel Production: Essential chromium source for 200, 300, and 400 series stainless steel.

  • Alloy Steel Manufacturing: Used in bearing steel, tool steel, and wear-resistant steel.

  • Foundry Industry: Used as an inoculant or alloy additive to enhance hardness and wear resistance.

  • Welding Electrodes/Flux: Serves as an alloying agent in flux.

  • Powder Metallurgy (PM): For manufacturing high-chromium alloy components.

  • Thermal Spray: For creating wear- and corrosion-resistant coatings.

  • Additive Manufacturing (3D Printing): Near-spherical ultra-low carbon FeCr powder for specialized parts.

4. Packaging & Storage

• Packaging:

  • Standard Sizes: Moisture-proof woven bags with inner plastic liner or jumbo bags.

  • Fine & Precision Powders: Vacuum-sealed, inert gas-filled aluminum foil bags, or steel drums.

• Storage: Store in a cool, dry, well-ventilated warehouse. Protect from moisture and oxidation. Avoid excessive stacking height.

5. Health & Safety

• Health Hazards: Chromium metal powder is generally considered low toxicity, but hexavalent chromium compounds are hazardous. Avoid prolonged or significant dust inhalation.

• Flammability: WARNING: Fine and ultra-fine FeCr powder can form explosive dust-air mixtures. Keep away from ignition sources and static electricity. Implement explosion-proof measures.

• Protective Measures: Operate with dust masks, safety glasses, and protective gloves. Ensure good workplace ventilation.
