Description
Achieve superior results in your machining and fabrication projects with the 34.9 mm (1 ³/₈″) 303 Stainless Steel Round Bar, a high-performance free-machining alloy designed for speed, accuracy, and long-lasting durability. Manufactured to precise tolerances, this solid stainless bar offers excellent machinability, allowing faster cutting, reduced tool wear, and smoother finishes — making it a favorite among CNC operators, fabricators, and engineers.
The 303 stainless steel grade is enhanced with sulfur to improve chip breaking and machining efficiency while maintaining strong corrosion resistance for use in both indoor and outdoor environments. This combination of properties makes it ideal for producing precision-engineered parts that demand strength, reliability, and a professional finish.
Whether you’re crafting gears, shafts, bushings, fasteners, or custom mechanical components, this precision-ready round bar delivers consistent performance across industrial, commercial, and DIY applications.
