Product Features & Benefits
- Superior Corrosion Resistance: The addition of molybdenum (2-3%) makes AISI 316 highly resistant to chlorides, acids, and industrial chemicals, ideal for marine and chemical environments.
- Hot Rolled & Pickled Surface: The pickling process removes scale and impurities, providing a clean, uniform surface that enhances weldability and paint adhesion.
- 2B Finish: A smooth, matte surface achieved by cold rolling after annealing, offering a balance of aesthetics and functionality for exposed applications.
- Precise Dimensions: 20mm diameter and 4m length with tight tolerances, suitable for machining, fabrication, and structural use.
- High Strength & Ductility: Excellent mechanical properties allow for easy forming, bending, and welding without compromising integrity.
- Long Service Life: Reduced maintenance costs due to excellent durability and resistance to pitting, crevice, and stress corrosion cracking.

Frequently Asked Questions (FAQ)
1. What is the difference between AISI 304 and AISI 316 stainless steel rod?
AISI 316 contains molybdenum, which gives it superior corrosion resistance, especially in chloride environments. It is more suitable for marine and chemical applications than 304.
2. Can this rod be welded easily?
Yes, AISI 316 has good weldability. Standard welding techniques (TIG, MIG, stick) can be used. Post-weld heat treatment is not generally required, but pickling may be needed to restore the surface finish.
3. Is the 2B finish suitable for food contact surfaces?
Yes, the 2B finish is smooth and non-porous, making it easy to clean and hygienic. It is commonly used in food processing equipment.
4. What tolerances do you maintain on the 20mm diameter?
We typically hold to ±0.1mm on diameter and ±5mm on length. Tighter tolerances are available upon request.
5. Do you provide a mill test certificate?
Yes, we can provide an EN 10204 3.1 mill test certificate with each shipment, confirming chemical composition and mechanical properties.
6. Can I order shorter lengths or custom diameters?
Absolutely. We offer custom cutting and sizing services. Minimum order quantities may apply, but we are flexible to meet your needs.
7. What packaging options are available?
Standard packaging includes bundles with steel straps, plastic caps, or wooden crates for export. Anti-rust paper and plastic wrapping are also available.
8. How long does delivery usually take?
For standard stock items, delivery typically takes 7–15 days. For custom orders, lead time is 20–30 days depending on quantity.
Backed by our ISO9001 certified quality management system and a strong export track record, Hemaokang Steel ensures that every stainless steel rod delivers consistent performance. Choose reliability, choose Hemaokang Steel for your next project.
