As a professional manufacturer in the stainless steel industry, Hemaokang Steel (Shandong) Co., Ltd. proudly presents our premium 310S Stainless Steel Round Bar with a diameter of 10mm and a length of 6 meters, featuring an annealed pickled surface. This product is designed to meet the highest standards of corrosion resistance and heat resistance, making it ideal for demanding industrial applications. Our commitment to quality and precision ensures that every bar delivers consistent performance, backed by our ISO9001 certification and extensive export experience.
The 310S stainless steel round bar is a high-temperature resistant alloy, containing 24-26% chromium and 19-22% nickel, which provides excellent oxidation resistance and creep strength. The annealed pickled surface finish removes scale and provides a clean, uniform appearance, enhancing corrosion resistance and facilitating further processing. Whether you need components for furnace parts, heat exchangers, or chemical processing equipment, this product offers reliable performance under extreme conditions.
Key Features & Benefits
- Exceptional Heat Resistance: Withstands continuous service temperatures up to 1150°C (2100°F), making it suitable for high-temperature environments.
- Outstanding Corrosion Resistance: Resists scaling and corrosion in both oxidizing and reducing atmospheres, even in harsh chemical environments.
- Annealed Pickled Surface: Provides a smooth, scale-free finish that enhances weldability and reduces the risk of localized corrosion.
- Precise Dimensions: Manufactured with tight tolerances (±0.1mm) to ensure consistent quality and easy integration into your projects.
- Versatile Length: Standard 6-meter length reduces waste and minimizes the need for joins, suitable for large-scale fabrication.
- ISO9001 Certified Quality: Our production processes are strictly controlled to meet international standards, ensuring reliable product performance.

Frequently Asked Questions
-
Q: What is the difference between 310S and 310 stainless steel?
A: 310S has a lower carbon content (max 0.08%) compared to standard 310 (max 0.25%), which improves weldability and reduces carbide precipitation during welding. It is preferred for applications requiring high-temperature strength and corrosion resistance. -
Q: Can you provide custom lengths other than 6 meters?
A: Yes, we can cut the bars to your specified lengths, such as 3m, 12m, or any custom size. Please contact us with your requirements. -
Q: Is the annealed pickled surface suitable for welding?
A: Absolutely. The pickled surface removes scale and oxides, providing a clean surface that promotes better weld quality and reduces the risk of weld defects. -
Q: What is the typical lead time for an order?
A: For standard sizes and quantities, lead time is usually 7-15 days after order confirmation. Larger quantities or custom sizes may require additional time. We can provide a specific timeline upon request. -
Q: Do you offer third-party inspection services?
A: Yes, we can arrange inspection by independent agencies such as SGS, BV, or TÜV at your cost. Our products are also subject to in-house quality control. -
Q: How do you package the round bars to prevent rust?
A: Our bars are packed in bundles with waterproof paper, plastic wrap, and steel strapping. For sea freight, we add anti-rust treatment and wooden crates if needed. -
Q: What is the minimum order quantity (MOQ)?
A: The MOQ for this product is 500 kg (approximately 84 pieces of 6m length). However, we can negotiate smaller quantities for trial orders. -
Q: Can you provide a mill test certificate (MTC)?
A: Yes, we provide MTC for each batch, detailing chemical composition and mechanical properties, as per EN 10204 3.1 or equivalent standard.
