Hemaokang Steel (Shandong) Co., Ltd. is proud to present our 316L Stainless Steel Rod 20mm for Food Processing Machinery, Hygienic Surface Finish. As a trusted manufacturer with an annual export value exceeding US$50 million, we specialize in delivering high-quality stainless steel products that meet the rigorous demands of the global food industry. Our 316L rods are engineered to provide exceptional corrosion resistance, easy cleanability, and long-lasting performance in sanitary environments, ensuring your food processing equipment operates safely and efficiently.
This product is specifically designed for applications where hygiene and durability are paramount. The 20mm diameter offers a balanced combination of strength and workability, while the mirror-like surface finish minimizes bacterial adhesion and simplifies cleaning procedures. Whether you are constructing conveyor systems, mixing tanks, or packaging machinery, our 316L rods deliver the reliability you need.
Below, we provide a detailed overview of the technical specifications, key benefits, and why Hemaokang Steel is your ideal partner for stainless steel solutions.
Product Features & Technical Specifications
- Superior Corrosion Resistance: 316L grade contains molybdenum, offering enhanced resistance to chlorides, acids, and alkalis commonly found in food processing environments. Perfect for contact with acidic foods, brines, and cleaning agents.
- Low Carbon Content (0.03% max): Reduces the risk of carbide precipitation during welding, maintaining corrosion resistance even in heat-affected zones. Ideal for fabrication of sanitary equipment.
- Hygienic Surface Finish: Our rods undergo precision polishing to achieve a surface roughness of Ra ≤ 0.4 μm (mirror finish) or as required. This smooth surface prevents product buildup and facilitates thorough cleaning, meeting FDA and EU sanitary standards.
- Precise Diameter Tolerance: Manufactured with tight tolerances (typically ±0.05mm) to ensure consistent fit in machining and assembly processes.
- Excellent Weldability & Formability: 316L can be easily welded, bent, and machined, allowing for versatile fabrication of custom components.
- Non-Magnetic in Annealed Condition: Suitable for equipment where magnetic interference must be avoided, such as in magnetic separators or sensitive electronic controls.
- Temperature Resistance: Maintains mechanical properties in cryogenic and high-temperature applications (up to 800°C in intermittent service).
Typical Mechanical Properties (20mm Rod)
| Property | Value |
|---|---|
| Tensile Strength (MPa) | ≥ 485 |
| Yield Strength (0.2% offset, MPa) | ≥ 170 |
| Elongation (% in 50mm) | ≥ 40 |
| Hardness (HRB) | ≤ 95 |
| Surface Roughness (Ra) | ≤ 0.4 μm (mirror) |
Key Benefits for Your Business
- Enhanced Food Safety: The hygienic surface finish reduces the risk of bacterial contamination, supporting compliance with HACCP and other food safety management systems.
- Reduced Maintenance Costs: Corrosion resistance and smooth surface minimize pitting, staining, and scale buildup, extending equipment life and lowering cleaning frequency.
- Versatile Machining: 20mm diameter is a standard size for shafts, rollers, guides, and structural supports in food machinery. Easily turned, drilled, or threaded to your exact specifications.
- Global Quality Assurance: Our ISO9001-certified facility ensures consistent quality from raw material selection to final inspection. Each rod is traceable and tested for chemical composition and mechanical properties.
- Customizable Lengths & Finishes: We offer cut-to-length services (up to 6m or longer) and various surface finishes (matte, brushed, mirror) to match your specific application requirements.

Frequently Asked Questions (FAQ)
-
Q: Is this 316L rod suitable for direct contact with food?
A: Yes, the 316L grade with a hygienic surface finish is commonly used in food contact surfaces. It complies with international sanitary standards (e.g., FDA, EU 1935/2004). However, we recommend confirming with your local regulations for specific applications. -
Q: What lengths are available for the 20mm rod?
A: Standard lengths are 3m and 6m. Custom lengths can be produced upon request, with a minimum order quantity. Please contact our sales team for details. -
Q: Can you provide a certificate of material testing?
A: Yes, we can provide a mill test certificate (MTC) per EN 10204 3.1 or 2.2, as well as third-party inspection reports if required. This is included in our standard quality assurance process. -
Q: What is the difference between 316L and 304 stainless steel for food machinery?
A: 316L offers superior corrosion resistance, especially against chlorides and acidic foods. It also has a lower carbon content, which reduces sensitization during welding. For harsh environments (e.g., cheese processing, seafood), 316L is preferred. -
Q: Does the rod come with a protective coating to prevent scratches during shipping?
A: Yes, we pack each rod individually with protective wrapping, and use wooden crates or bundles to ensure the surface finish remains intact. Additional packaging options are available upon request. -
Q: Is the 20mm rod magnetic?
A: In the annealed condition, 316L is generally non-magnetic. However, cold working can induce slight magnetism. If non-magnetic properties are critical, please specify your requirements, and we can adjust the processing accordingly. -
Q: What is the typical lead time for an order of 1000 kg of 20mm rods?
A: For standard sizes and finishes, lead time is approximately 15–25 working days, depending on order volume and current production schedule. Rush orders may be possible with prior arrangement. -
Q: Can you provide samples before bulk purchase?
A: Absolutely. We offer free samples (up to 1 meter length) for quality evaluation. The customer pays only for shipping. Please contact our sales team to request a sample.
