Product Overview

304 Stainless Steel Round Bar is the most widely used austenitic stainless solid round bar, equivalent grade 1.4301, SUS304 and 06Cr19Ni10. It is produced following GB/T1220, ASTM A276, ASTM A484 and EN10088-3 standards. We supply two types: hot rolled black surface bar for heavy machining, and cold drawn bright & precision ground round bar for high-precision applications. Hot rolled bar covers Φ16mm~Φ300mm, cold drawn bar Φ3mm~Φ120mm, tolerance up to ±0.01mm. Surface options include polishing, turning and peeling. Standard lengths 3m,6m,12m. It is commonly used for food machinery, general chemical equipment, pump & valve parts, architectural components and general mechanical manufacturing.
