Brian Fasteners, with a presence in Houston, USA, produces and provides Stainless Steel 303 bars and rods through precision forging and machining operations. SS 303 is a sulfur/phosphorus containing free-machining austenitic alloy. Brian Fasteners makes sure each bar adheres to tight dimensional tolerances and surface finish requirements. Supplied to the automotive, fastener, and general engineering industries, the firm provides bespoke lengths, quick turnaround times, and technical advice. Through the supply of consistent, high-quality SS 303 rods and bars, Brian Fasteners delivers reliable raw material for mass-production use where efficient machining is needed.
Stainless Steel 303 has 17–19% chromium, 8–10% nickel, with sulfur/phosphorus additions (~0.15%) for increasing machinability. The carbon content is up to 0.15%. It has tensile strength of 550–750 MPa, yield strength 250–350 MPa, and elongation of 30–40%. Though corrosion resistance is somewhat less than 304, SS 303 provides the ease of machining that renders it suitable for components with complex geometries and limited finishing.

Stainless Steel 303 Bars and Rods are commonly used in industries such as aerospace, automotive, medical, and manufacturing. They are perfect for producing components like fasteners, surgical instruments, fuel lines, and machinery parts.
Yes, Stainless Steel 303 Bars and Rods offer excellent corrosion resistance, particularly against a range of acids, chemicals, and weathering, making them suitable for use in both industrial and outdoor environments.
Stainless Steel 303 Bars and Rods are specifically designed for excellent machinability due to the addition of sulfur and phosphorus, which improve cutting and machining performance. This makes them ideal for high-precision applications like fasteners, shafts, and gears.
Brian Fasteners‘ SS 303 rods are commonly utilized in fasteners, studs, shafts, gears, and bushings with effective machining. They are selected for valve parts, instrument components, and screws where close tolerances are crucial. When used in mass production, its superior machinability reduces tool life and cycle times. While less appropriate to harsh corrosive conditions, SS 303 bars assist in general-purpose industrial uses, precision components, and automotive components. Brian Fasteners guarantees quality supply for production-led machining efficiency.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
