Frequently Asked Questions (FAQ)
Q1: What is the difference between cold drawn and hot rolled stainless steel rods?
A: Cold drawn rods have tighter tolerances, a smoother surface, and higher tensile strength compared to hot rolled. They are ideal for precision applications where dimensional accuracy is critical.
Q2: Are these rods suitable for food-grade applications?
A: 304 stainless steel is generally considered food-safe and resistant to organic acids. However, for direct food contact, we recommend confirming with local regulations. Additional surface treatments (e.g., electropolishing) can be provided.
Q3: Can I get rods with a different diameter, e.g., 5mm or 6mm?
A: Yes, we can produce custom diameters from 1mm up to 100mm upon request. Please contact our sales team with your specific requirements.
Q4: What length options are available?
A: Standard lengths are 3m and 6m. We also offer custom cut lengths per your order, with minimum quantity conditions.
Q5: Do you provide any certificates of material?
A: Yes, we can provide a mill test certificate (MTC) for each batch, confirming compliance with ASTM A276 and other standards. ISO9001 certification is also available upon request.
Q6: How is the surface finish – is it bright or matte?
A: The cold drawn process produces a bright, smooth surface. If you require a matte or brushed finish, we can offer additional surface treatment options.
Q7: What is the minimum order quantity (MOQ)?
A: MOQ varies by diameter. For popular sizes like 1mm-4mm, MOQ is typically 100 kg. For smaller orders, please inquire.
Q8: How do you pack the rods for export?
A: Rods are packed in bundles with steel straps, then wrapped in waterproof paper or plastic, and placed in wooden crates or pallets to ensure safe transport.
