Product Definition：
Stainless steel bars are long, solid products manufactured from stainless steel billets through hot rolling, cold drawing, or forging processes. They serve as semi-finished materials for machining, fabrication, and construction applications, combining high strength, excellent corrosion resistance, and good machinability.
Key Characteristics：
| Feature | Description |
|---|---|
| Corrosion Resistance | Excellent resistance to rust, pitting, and chemical attack – grade dependent |
| High Strength | Good mechanical properties with moderate weight |
| Machinability | Free-machining grades (303, 416) available for high-volume production |
| Heat Treatable | Martensitic (410, 420) and PH (17-4PH) grades can be heat treated for higher hardness |
| Weldability | Austenitic grades (304, 316) offer excellent weldability |
| Dimensional Accuracy | Cold drawn and ground bars achieve tight tolerances (h9/h11/h6) |
| Surface Quality | Multiple finishes – from black to mirror polished |
| 100% Recyclable | Environmentally friendly with no loss of properties |
Product Forms Overview：
| Shape | Description | Size Range | Best For |
|---|---|---|---|
| Round Bar | Cylindrical cross-section | Ø3 – Ø500 mm | Shafts, turned parts, general machining |
| Square Bar | Four equal sides | 3×3 – 200×200 mm | Structural, fasteners, tooling |
| Hex Bar | Six-sided, across-flats dimension | AF5 – AF100 mm | Bolts, nuts, fasteners, automatic lathe |
