Description:
304 Stainless Steel Bright Round Bar, also known as "Guang Yuan," is a precision-engineered cold-drawn or polished bar with a smooth, mirror-like surface finish. Ideal for applications requiring corrosion resistance, aesthetic appeal, and mechanical reliability, this austenitic stainless steel grade is widely used in industrial, architectural, and precision engineering sectors.

Key Features:

1. Superior Corrosion Resistance:

   • Chromium (18-20%) and nickel (8-10.5%) form a self-repairing passive oxide layer, resisting oxidation, acids, and chloride environments 16.

   • Performs well in atmospheric, freshwater, and mild chemical exposures.

2. Mechanical Properties:

   • Tensile Strength: ≥515 MPa

   • Yield Strength: ≥205 MPa

   • Elongation: ≥40%

   • Hardness: ≤187 HB 7

3. Surface Options:

   • Bright (Mirror) Finish: Cold-drawn or centerless-ground for precision dimensions.

   • Polished: Electrolytic or mechanical polishing for enhanced smoothness 68.

   • Custom finishes available upon request 5.

4. Sizes & Specifications:

   • Diameter: Φ3mm–Φ500mm (standard range: Φ3–Φ30mm for precision applications) 58.

   • Length: 3m, 4m, 6m (standard) or custom-cut lengths.

5. Processing Flexibility:

   • Supports laser/plasma cutting, bending, welding (TIG/MIG), threading, and CNC machining 56.

   • Available in hot-rolled, cold-drawn, or forged forms 8.

Applications:

• Automotive & Aerospace: Shafts, fasteners, valve components 16.

• Construction: Structural frameworks, decorative trims, railings 68.

• Food & Medical: Equipment for hygiene-critical environments (e.g., surgical tools, processing machinery) 37.

• Energy & Chemicals: Components for nuclear, petrochemical, and marine industries 68.

Certifications & Quality Assurance:

• Mill Test Certificates (EN 10204 3.1/3.2) 6.

• ISO 9001:2000 certified manufacturing processes 8.

Packaging & Delivery:

• PVC-wrapped bundles or wooden crates with anti-rust protection.

• MOQ: 10 kg (flexible for bulk orders) 510.

• Lead Time: 7–15 days (stock sizes); 3–4 weeks (custom orders).

Supplier Details:

• Manufacturer: Foshan Guoju Stainless Steel Co., Ltd. (Guangdong, China) 68.

• Export Markets: USA, EU, Southeast Asia, etc.
