1. Additive Manufacturing (3D Printing)
    Processes: Selective Laser Melting (SLM), Electron Beam Melting (EBM).
    Advantages: Low carbon content (≤0.03%) minimizes carbide precipitation, making it suitable for welded components.
    Typical Products: Aerospace components, medical implants (post-processing required), customized industrial parts.

2. Metal Injection Molding (MIM)
    Advantages: Ideal for small, complex parts with high precision.
    Typical Products: Watch cases, surgical tools, electronic connectors.

3. Surface Engineering & Coatings
    Techniques: Thermal spraying (plasma, HVOF) for surface enhancement.
    Advantages: Improves corrosion and wear resistance.
    Applications: Chemical processing equipment, marine components.

4. Powder Metallurgy (PM)
    Process: Pressing and sintering to produce near-net-shape parts.
    Advantages: High material efficiency, cost-effective for mass production.
    Typical Products: Automotive fuel injectors, filters, corrosion-resistant flanges.

5. Chemical & Energy Industries
    Properties: Resistant to acids and alkalis.
    Applications: Reactor linings, valves, pump components.

6. Research & Development
    Focus: Alloy modification, composite materials (e.g., ceramic-reinforced powders).
