    Excellent corrosion resistance 
    Grades AISI 304 / 304L resist water, humidity and mild acid-base erosion; 316L with molybdenum performs well in seawater, chemical and salt spray environments. No anti-rust paint needed, greatly lowering long-term maintenance costs.

    Stable mechanical performance 
    High tensile strength, good hardness and toughness. It can be turned, milled, drilled, forged, bent and welded without easy fracture or deformation.

    Multiple shape options for flexible machining 
    Available in round bar, square bar, flat bar, hexagonal bar, octagonal bar to match different mechanical connection and structural requirements.

    Clean & hygienic surface 
    Polished bright surface is smooth and non-porous, free of bacteria residue. 304 grade meets global food and pharmaceutical contact standards.

    Wide temperature adaptability 
    Maintain stable performance under both low-temperature and high-temperature working conditions, not easy to soften or brittle.

    Long service life 
    Indoor service life over 25 years; outdoor damp environment can last more than 15 years, far superior to carbon steel bars.

    Customizable tolerance & surface finish 
    Precision bright bars achieve ultra-tight dimensional tolerance; optional finishes include hot rolled black skin, pickled matte, 2B polished, mirror polishing.

    Eco-friendly & recyclable 
    100% recyclable metal without toxic precipitation, compliant with export environmental standards of Turkey, Africa and Europe.

    Low trial MOQ & flexible delivery 
    Support small sample orders, fixed-length cutting and customized diameter as customer drawings, with sufficient stock for fast shipment.

Manufacturing Process of Stainless Steel Bar

Step 1 Smelting & Continuous Casting
    Alloy elements (Cr, Ni, Mn, C, Mo) are proportionally melted according to target grade, then continuously cast into stainless steel square billets.

Step 2 Hot Rolling (for hot rolled black bar)
    Steel billets are heated above 1100℃ and hot rolled through multiple passes into rough bars of required diameter. Straightening machine removes bending deformation.

Step 3 Pickling Descaling
    Hot rolled bars are soaked in acid pool to remove high-temperature oxide scale, then passivated to form a uniform anti-rust protective film.

Step 4 Cold Drawing / Cold Rolling (for bright precision bar)
    Hot rolled semi-finished bars go through surface grinding, then cold drawn by drawing machine to reduce diameter and achieve tight tolerance, smooth bright surface.

Step 5 Stress Relief Annealing
    Cold-worked bars are annealed under nitrogen protection to eliminate internal stress and improve machinability for subsequent cutting & turning.

Step 6 Surface Finishing
    Optional processing: rough pickled finish, fine grinding, mirror polishing, centerless polishing for ultra-smooth bright surface.

Step 7 Fixed-length Cutting & Deburring
    Cut bars to standard 6m or customized length, remove burrs on both ends for precise assembly.

Step 8 Full Inspection & Export Packing
    Inspect diameter tolerance, surface quality, mechanical property and metallurgical composition, issue official Mill Test Certificate (MTR). Wrap with VCI anti-rust paper, bind into bundles, load on IPPC fumigated wooden pallets or sealed wooden cases for sea shipment.
