Wear Resistant
Material Properties of Stainless Steel:
Stainless steel is an iron-based alloy containing a minimum of
10.5% chromium, which forms a passive oxide layer on the surface,
providing excellent corrosion resistance. Other alloying elements,
such as nickel, molybdenum, and manganese, enhance specific
properties like strength, ductility, and heat resistance. Common
stainless steel grades used in casting include:
304 Stainless Steel: Offers excellent corrosion resistance and weldability, ideal for
food processing and architectural applications.
316 Stainless Steel: Contains molybdenum for superior resistance to chlorides, making
it suitable for marine and medical environments.
430 Stainless Steel: A cost-effective option with good corrosion resistance, often used
in automotive and industrial applications.
17-4 PH Stainless Steel: A precipitation-hardening grade with high strength and hardness,
used in aerospace and high-stress components.
2205 Duplex Stainless Steel: Combines high strength with excellent resistance to stress
corrosion cracking, ideal for oil and gas industries.
Comparison of Stainless Steel Casting with Other Manufacturing
Methods:
Aspect | Stainless Steel Casting | Machining | Forging | Plastic Molding |
|---|
| Material Strength | High (excellent mechanical properties) | High (but material loss) | Very High (grain alignment) | Low (limited strength) |
| Complexity of Shapes | High (can produce intricate designs) | Moderate (limited by tooling) | Low (simple shapes) | High (but limited by material) |
| Cost for High Volume | Moderate to High | High (labor-intensive) | High (tooling costs) | Low (for large volumes) |
| Corrosion Resistance | Excellent (inherent in stainless steel) | Depends on material | Depends on material | Moderate (varies by plastic) |
| Surface Finish | Good (can be improved with post-processing) | Excellent (smooth finish) | Moderate (requires finishing) | Good (mold-dependent) |
| Lead Time | Moderate (mold creation required) | Short (for small batches) | Moderate to Long | Short (for large volumes) |
