Product Features & Benefits
Superior Anti-Rust Performance: The AISI 304 grade contains 18% chromium and 8% nickel, forming a passive oxide layer that resists oxidation and corrosion in humid or mildly aggressive environments. This ensures your machined parts maintain their appearance and structural integrity over time.
Excellent Machinability: The annealed condition provides a balanced hardness that allows for efficient cutting, drilling, milling, and turning. Reduced tool wear and lower cutting forces translate to higher throughput and lower production costs.
Precise Hexagonal Geometry: Our hex bars are drawn or extruded to tight tolerances, ensuring consistent flat-to-flat dimensions and sharp corners. This uniformity simplifies clamping and alignment in CNC machines and manual setups.
Versatile Application Range: Ideal for manufacturing custom fasteners, bolts, nuts, connectors, shafts, spacers, and other precision hardware components. Suitable for automotive, construction, marine, food processing, and general industrial equipment.
Customizable Lengths & Sizes: We offer flexible cutting and sizing options to meet your specific production requirements. Bulk orders can be supplied in standard lengths or cut-to-size blanks.
Consistent Mechanical Properties: Each batch is tested for chemical composition, hardness, and tensile strength to ensure compliance with ASTM A276. Our quality control procedures guarantee lot-to-lot consistency.
Environmentally Friendly Packaging: Bars are bundled with protective paper or plastic interleaving to prevent surface scratches during transit, and are packed in reinforced wooden crates or steel frames for export.

Frequently Asked Questions (FAQ)
Q: What is the difference between AISI 304 and 304L stainless steel hex bars?
A: AISI 304 has a carbon content of up to 0.08%, while 304L has a maximum of 0.03%. The lower carbon in 304L reduces the risk of sensitization during welding, but for hardware machining parts that do not involve heavy welding, standard AISI 304 offers excellent corrosion resistance and higher strength. We can supply 304L upon request.Q: Can you provide hex bars with a specific surface finish, such as polished or brushed?
A: Yes, we offer custom surface treatments including bright annealed, pickled, and passivated finishes. For polished or brushed surfaces, please discuss your requirements with our sales team, and we will evaluate feasibility.Q: What is the typical lead time for bulk orders of AISI 304 hex bars?
A: For standard sizes and quantities, the lead time is approximately 15–25 working days from order confirmation. Custom sizes or special finishes may require 25–40 working days. We prioritize urgent orders based on inventory availability.Q: Do you provide mill test certificates or material test reports?
A: Absolutely. Each shipment is accompanied by a mill test certificate (MTC) per EN 10204 3.1 or equivalent, detailing chemical composition, mechanical properties, and dimensions. Additional third-party inspection is available upon request.Q: What packaging options are available for export?
A: We use protective wrapping (paper or plastic) between layers, then bundle the bars with steel straps. For sea freight, we pack in wooden crates or steel frames to prevent damage. Custom packaging with your logo or special markings can be arranged.Q: Can I get a sample before placing a large order?
A: Yes, we offer free samples for standard sizes (customer pays shipping) and can produce small quantities for evaluation. Please contact us to discuss your sample needs.Q: Are there any minimum order quantities (MOQ) for hex bars?
A: For standard sizes, the MOQ is typically 500 kg per size. For non-standard sizes or special finishes, the MOQ may be higher. We can discuss flexibility for trial orders.Q: How do you ensure the anti-rust property of the hex bars during storage and transportation?
A: Our bars are passivated after manufacturing to enhance the chromium oxide layer. They are then stored in a dry, ventilated warehouse. During transportation, we use moisture-proof packaging and desiccants when necessary. Please follow standard storage practices to maintain the surface condition.
