304 Stainless Steel Bright Round Bar, commonly referred to as "Guang Yuan" in industrial markets, is a premium-grade austenitic stainless steel product engineered for precision-critical applications. Featuring a seamless cold-drawn or precision-ground surface, this bar combines aesthetic appeal with unmatched mechanical integrity in corrosive or high-stress environments.
Ultra-Smooth Finish: Achieved through multi-stage polishing (Ra ≤0.4μm), reducing friction and wear in dynamic applications.
Zero-Tolerance Precision: Diameter tolerance ±0.02mm for sizes ≤30mm (customizable to ±0.005mm).
Eco-Certified: Compliant with RoHS and REACH regulations for hazardous substance control.
