Based in Amman, Jordan, Sabra Metals is a reliable manufacturer and supplier known for its high-quality Stainless Steel 303 Hex Bars and Rods, perfect for precision machining and fastener applications. These hex bars are crafted from sulfur-alloyed austenitic stainless steel, ensuring excellent machinability and consistent dimensional accuracy. Sabra Metals takes quality control seriously, overseeing chemical composition, surface finish, and hexagonal tolerances to meet international standards. With state-of-the-art manufacturing facilities and a dependable supply chain, the company caters to the automotive, engineering, fastener manufacturing, and precision component industries around the globe.
Stainless Steel 303 Hex Bars and Rods are made up of chromium (17–19%), nickel (8–10%), and a touch of sulfur to enhance machinability. This unique alloy composition allows for quicker cutting speeds and efficient chip formation. In terms of mechanical properties, SS 303 boasts good tensile strength, moderate yield strength, and stable hardness. While its corrosion resistance is a bit lower than that of SS 304, it still performs well in mildly corrosive environments. The material also offers good ductility and dimensional stability, making it ideal for precision-machined components.

Stainless Steel 303 offers excellent machinability due to sulfur addition, good corrosion resistance, high toughness, and decent strength. It's ideal for precision machining, retaining mechanical properties while being easily cut.
Stainless Steel 303 has superior machinability due to added sulfur but slightly reduced corrosion resistance compared to 304 or 316. It balances easy machining with moderate corrosion resistance for non-critical environments.
Common finishes for Stainless Steel 303 hex bars/rods include polished, brushed, and matte finishes. Treatments like passivation improve corrosion resistance, while electropolishing enhances durability and appearance. Protective coatings and bead blasting offer additional surface refinement options.
Stainless Steel 303 Hex Bars and Rods find their place in a variety of applications that demand extensive machining and tight tolerances. They are commonly used for bolts, nuts, screws, studs, shafts, fittings, and precision fasteners. These hex bars are heavily utilized in automotive assemblies, industrial machinery, electrical equipment, and general engineering projects. SS 303 hex bars are particularly favored for parts made on automatic screw machines, where high productivity, dimensional accuracy, and a smooth surface finish are crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
