Below you'll find a detailed overview of the product specifications and benefits.
Key Features & Technical Specifications
Material Grade: Lean austenitic stainless steels (e.g., 304L, 316L, 321, 347) – optimized for reduced carbon content to minimize sensitization and improve weldability.
Shape Options: Round bar (diameter 6–300 mm), Square bar (5–100 mm), Hexagonal bar (5–100 mm across flats). All shapes available in straight lengths or cut-to-size.
Surface Finish: Bright (cold drawn), polished (up to 400 grit), peeled, or turned – customizable per your application (e.g., food processing, chemical equipment).
Tolerances: Precision ground to H9/H10/H11 (round) or as per customer drawing; square/hex bars produced with sharp corners and consistent dimensions.
Mechanical Properties: Typical tensile strength 515–720 MPa, yield strength ≥205 MPa, elongation ≥35% (varies by grade and treatment).
Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking – ideal for harsh environments.
Heat Treatment: Solution annealed and quenched for optimal microstructure; optional stabilization treatment for grades like 321.
Common Dimensions & Weight Table (Round Bar Example)
| Diameter (mm) | Weight per meter (kg/m) | Tolerance (mm) | Standard Length (m) |
|---|---|---|---|
| 10 | 0.62 | ±0.05 | 6 |
| 25 | 3.87 | ±0.10 | 6 |
| 50 | 15.5 | ±0.15 | 6 |
| 100 | 62.0 | ±0.25 | 12 |
Note: Square and hexagonal bars are supplied in equivalent size ranges. We can also source non-standard dimensions and special grades upon request. All products are traceable to mill test certificates.
Why Choose Wuxi Yansheng for Your Engineering Projects?
Reliable Quality: Our manufacturing processes are certified under multiple international standards including ISO9001, ISO14000, OHSAS18001 and industry-specific certifications like HACCP, TL900, SA8000. Every batch undergoes rigorous inspection – hardness test, dimensional check, and spectroscopic analysis.
Customization Flexibility: Need a specific chamfer, surface roughness, or length? Our engineering team can adapt the production to match your drawings. Custom sizes and shapes (e.g., flat bar, angle) are also available.
Competitive Lead Times: With a 101–200 person workforce and a well-organized factory, we typically ship within 15–25 days after order confirmation. For urgent projects, expedited service is possible.
Global Logistics Network: We ship from major Chinese ports (Tianjin, Shanghai, Qingdao, Ningbo) and have successfully delivered to North America, South America, Europe, Southeast Asia, Africa, Oceania, the Middle East, and more.

Frequently Asked Questions
Q: What is the difference between lean austenitic and standard 304 stainless steel bar?
A: Lean austenitic grades (e.g., 304L) have reduced carbon content (typically ≤0.03%) to minimize carbide precipitation during welding, reducing the risk of intergranular corrosion. They also may contain nitrogen for added strength. This makes them ideal for thick-section welding applications.Q: Can you supply square and hexagonal bars with sharp corners?
A: Yes, our square and hexagonal bars are manufactured with precise corner radius control. We can deliver with sharp or slightly radiused corners depending on your requirement. Please specify when ordering.Q: Do you provide material certificates?
A: Absolutely. Each shipment comes with a Mill Test Certificate (EN 10204 3.1) showing chemical composition and mechanical properties. Third-party inspection reports are also available upon request.Q: What is the typical surface finish for engineering applications?
A: Most engineering customers prefer cold drawn (bright) or peeled finish for improved dimensional accuracy. Polished finish (up to 400 grit) is common for food or pharmaceutical equipment. We can also supply hot-rolled (black) finish for non-critical uses.Q: How do you ensure straightness for long bars?
A: After rolling and drawing, bars undergo straightening using multi-roller straighteners. For high-straightness requirements (e.g., 0.5mm/m), we can apply additional rotary straightening. Please consult our technical team for specific needs.Q: What payment terms do you accept?
A: We accept T/T, L/C, and sometimes D/P. For new customers, a 30% deposit and 70% against copy of shipping documents is typical. Flexible terms can be discussed for large or regular orders.Q: Can you supply bars in custom lengths longer than 12 meters?
A: Standard maximum length is 12 meters due to shipping container constraints. For longer lengths, we can arrange special packaging (e.g., flat rack containers) or provide joint welding services (with buyer’s approval). Contact us for feasibility.Q: Do you have inventory of common sizes ready for quick delivery?
A: Yes, we maintain a stock of popular sizes (e.g., round 10mm, 20mm, 30mm, 50mm; square/hex 10mm, 20mm, 30mm) in grades 304L and 316L. Small quantities can be dispatched within 7 days. Larger quantities require production lead time.
