Product Information:

The 303 Stainless Steel Rod (also known as Alloy 303 or 303F) is a high-performance, corrosion-resistant metal designed for various industrial and commercial applications. With excellent machinability and good surface finish, 303 stainless steel rods are widely used for precision components that require a high level of strength, durability, and aesthetic appeal.

Technical Parameters:

• Material: Stainless Steel (Grade 303, 303F)

• Diameter Range: 3mm to 200mm (custom sizes available)

• Length: Up to 4 meters (can be cut to customer specifications)

• Finish: Bright Polished, Mirror Finish (Various surface finishes available)

• Density: 7.90 g/cm³

• Tensile Strength: 500 MPa (minimum)

• Yield Strength: 215 MPa (minimum)

• Elongation: 40% (minimum)

• Hardness: Brinell Hardness 201

• Thermal Conductivity: 16.2 W/m·K

• Electrical Resistivity: 0.73 x 10⁻⁶ Ω·m

Performance Features:

• Excellent Machinability: The addition of sulfur in Alloy 303 improves its machinability, making it ideal for high-speed machining operations, especially when precise cutting and shaping are required.

• Corrosion Resistance: While 303 offers good resistance to atmospheric and mild chemical corrosion, it is particularly suited for environments where low corrosion resistance is required in the form of parts that need to maintain strength without undergoing excessive corrosion.

• Good Surface Finish: The bright polished finish of 303 stainless steel ensures a smooth, visually appealing surface, making it ideal for use in decorative applications.

• Non-magnetic: 303 stainless steel is generally non-magnetic in the annealed condition, although slight magnetism may develop during cold working.

• Workability: Superior cold working properties, such as forming, bending, and welding, make 303 stainless steel rods versatile for a wide range of applications.

Standards:

• ASTM A276 – Standard Specification for Stainless Steel Bars and Shapes

• ASTM A479 – Standard Specification for Stainless Steel Bars for Use in Boilers and Other Pressure Vessels

• ISO 3506-1 – Stainless Steel Fasteners – Part 1: Bolts, Screws, and Studs

• UNS S30300 – Unified Numbering System for Stainless Steel Grades

• DIN 17440 – Stainless Steel Bars and Rods

Key Features:

1. High Strength: Excellent mechanical properties, including tensile strength and yield strength, make 303 stainless steel ideal for load-bearing applications.

2. High Machinability: Designed for easy machining with high-speed tools, 303 is a go-to material for parts requiring precision turning, threading, and milling.

3. Bright Polished Surface: Achieves a sleek, attractive, and highly reflective surface, ensuring a premium finish for aesthetic applications.

4. Corrosion Resistance: Good general corrosion resistance, particularly in industrial and mild environments.

5. Non-Magnetic: Minimizes magnetic interference in specific applications such as electronic equipment and sensors.

Applications:

• Automotive Industry: Used in manufacturing precision components such as bolts, nuts, shafts, and fasteners that demand both strength and corrosion resistance.

• Aerospace: Employed in the production of lightweight, high-strength components, including brackets, fittings, and structural elements.

• Food Processing Equipment: Suitable for manufacturing parts in contact with food due to its corrosion resistance and non-reactivity with food products.

• Medical Devices: Ideal for medical instruments, surgical tools, and implants that require high strength, precision, and biocompatibility.

• Electronics: Used in the fabrication of non-magnetic components like connectors, housing, and pins for electrical devices.

• Marine Industry: Recommended for parts exposed to moderate corrosion, such as shafts, fasteners, and bolts.
