| Alloy Types | Features & Uses |
|---|---|
| 303 (CF16F) | Most machinable austenitic steel, lower corrosion resistance. Used for gears, bushings, hardware fittings in automotive and construction. |
| 304 (CF8) | Excellent corrosion resistance, easy to fabricate. Ideal for valve bodies, pump components, and railway fittings. |
| 304L (CF3) | Low carbon to resist carbide precipitation, excellent formability. Suits automotive exhausts, construction hardware, and pump parts. |
| 309 (CH20) | High heat resistance up to 1038°C, oxidation-proof. Used in aerospace exhausts, valve components, and marine heat shields. |
| 310 (CK20) | Oxidation resistance through 1093°C, tough at cryogenic temperatures. Applied in aerospace structures, valve housings, and railway parts. |
| 316 (CF8M) | Superior corrosion resistance against salt and chlorides. Perfect for marine environments, petrochemical, and automotive parts. |
| 316L (CF3M) | High nickel and molybdenum, immune to sensitization. Used in marine fittings, aerospace brackets, and heavy-duty pump parts. |
| 347 (CF8C) | Oxidation-resistant, stable at high temperatures. Suits aerospace engine parts, train exhaust systems, and valve assemblies. |
