What does manganese do to metals?
Manganese is primarily used as an alloying agent and purifier. Its effects are fundamental to modern metallurgy, especially in iron and steel production. Here’s what it does:
When Added to Iron/Steel:
- 1.
Deoxidizer and Desulfurizer (Most Important Function):
- •Deoxidation: Manganese has a high affinity for oxygen. It reacts with oxygen in the molten steel to form manganese oxide (MnO), which floats to the top as slag. This removes harmful oxygen bubbles (which cause weakness and brittleness) and results in a stronger, more uniform steel.
- •Desulfurization: It also has a high affinity for sulfur. It reacts with sulfur to form manganese sulfide (MnS). This is crucial because iron sulfide (FeS) causes a defect called "hot shortness," making the steel brittle and prone to cracking when hot-rolled or forged. MnS is less harmful and remains in particulate form, preventing brittleness.
- 2.
Alloying Agent (Enhancing Properties):
- •Increases Strength and Toughness: Manganese atoms strengthen the iron's crystal lattice (solid solution strengthening), making the final steel significantly stronger and tougher without sacrificing ductility.
- •Improves Hardness and Wear Resistance: This is the key property in "Hadfield Steel" (11-14% Mn). This steel becomes incredibly hard and wear-resistant upon impact (work-hardening), making it ideal for rock crushers, railway crosspoints, and armor.
- •Promotes Hardenability: Manganese allows steel to be heat-treated more effectively, enabling a deeper and more uniform hardness after quenching.
When Added to Aluminum:
- •Increases Strength: It forms a fine dispersion of intermetallic compounds that strengthen the aluminum through dispersion strengthening.
- •Improves Corrosion Resistance: The manganese-rich particles help make the alloy more resistant to corrosion.
In summary, manganese is not just an additive; it's a vital purifier and transformative agent that turns brittle, impure iron into the strong, workable steel that defines modern infrastructure and manufacturing. Its role in high-purity forms like EMM is equally critical for advanced technology like EVs.
