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
