The bright annealed finish not only improves the rod's appearance but also enhances its resistance to oxidation and pitting. This makes our rods particularly suitable for pharmaceutical equipment, semiconductor manufacturing, and high-end kitchenware. The low carbon content of 316L minimizes carbide precipitation during welding, ensuring long-term durability in corrosive environments. Customers benefit from consistent quality batch after batch, thanks to our rigorous in-house testing and third-party verification.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between 316 and 316L stainless steel rod?
A: 316L has a lower carbon content (≤0.03%) compared to 316 (≤0.08%). This reduces the risk of intergranular corrosion after welding, making 316L the preferred choice for heavy welding applications. -
Q: Can you provide custom lengths or diameters beyond 0.5mm–2mm?
A: Yes, we offer custom sizes upon request. Please contact us with your specific requirements, and we can adjust production accordingly. -
Q: Are the rods suitable for food contact applications?
A: Absolutely. 316L is FDA-compliant for food contact surfaces, and the bright annealed finish provides a smooth, non-porous surface that is easy to clean and sanitize. -
Q: Do you offer mill test certificates or third-party inspection reports?
A: Yes, we provide mill test certificates (MTC) with every shipment. Third-party inspection (e.g., SGS, BV) can also be arranged at an additional cost. -
Q: What is the typical lead time for orders?
A: For standard diameters and lengths, we can ship within 7–10 working days. Custom orders may require 15–20 working days, depending on quantity. -
Q: How do you package the rods to prevent damage during transit?
A: We bundle rods with plastic caps, wrap them in protective paper, and pack them in sturdy wooden crates or pallets. For overseas shipments, we use fumigation-free wood packaging. -
Q: Can I request a free sample before placing a bulk order?
A: Yes, we offer free samples (up to 1 meter per diameter) for quality evaluation. You only need to pay for shipping costs. -
Q: What is your minimum order quantity (MOQ)?
A: The MOQ for standard sizes is 100 kg per diameter. For custom sizes, MOQ may vary – please consult our sales team.
