George Metals, a reputable manufacturer and supplier located in Houston, USA, specializes in high-precision Stainless Steel 303 Hex Bars and Rods, celebrated for their outstanding machinability and resistance to corrosion. This particular grade of stainless steel is a free-machining austenitic type, crafted to enhance cutting and threading efficiency while still providing solid strength and oxidation resistance. Adhering to ASTM A582 standards, these hex bars and rods are perfect for applications that demand tight tolerances and a superior finish. George Metals offers 303 hex bars in a variety of sizes and custom lengths, catering to industries like automotive, aerospace, mechanical engineering, and general-purpose machining
Stainless Steel 303 Hex Bars and Rods consist of 17–19% Chromium, 8–10% Nickel, and a minimum of 0.15% sulfur to boost machinability. While they are slightly less resistant to corrosion than 304, 303 still boasts impressive mechanical properties, with tensile strength ranging from 500–750 MPa and high machinability ratings. This grade cannot be hardened through heat treatment but retains good toughness and surface quality. George Metals guarantees consistent metallurgical quality, precise dimensions, and excellent surface finish, making their 303 hex bars perfect for high-speed machining, threading, and precision components.
