Premium 304 Stainless Steel Bar for Global Applications

TISCO Steel Group (Jiangsu) Co., Limited is your trusted partner and authorized distributor for premium-grade stainless steel products in China. We specialize in supplying high-quality 304 Stainless Steel Bars sourced directly from the world’s most reputable mills, including TISCO (Taiyuan Iron and Steel), Tsingshan, BAOSTEEL, and ANSTEEL. This direct partnership allows us to guarantee material authenticity, provide full Mill Test Certification (MTC) traceable to the origin, and offer highly competitive pricing without compromising on quality.

Why Choose Our 304 Stainless Steel Bar?

The 304 (UNS S30400) grade is the most versatile and widely used austenitic stainless steel. It offers an excellent balance of:

Excellent Corrosion Resistance: With a high chromium-nickel content, it resists a wide range of atmospheric environments, many corrosive media, and is ideal for use in mild chemical, food processing, and marine applications.
Good Mechanical Properties: It boasts impressive strength, toughness, and durability, making it suitable for machining and fabrication into various components.
Ease of Fabrication & Welding: It can be readily machined, welded, and formed using standard methods, reducing overall production time and costs.

A Note on Limitations:
While 304 offers outstanding value, it is less resistant to chlorides (e.g., saltwater) than 316 stainless steel. For applications involving intense corrosives or marine environments, we often recommend considering our 316 bars.

We provide cold-finished and hot-finished 304 bars in round, square, hex, and flat shapes, tailored to your precise specifications. Our rigorous quality control ensures every bar meets international standards, providing you with reliable performance in your machining, construction, automotive, and food machinery projects.

2. What is the price of 304 stainless steel bar?
The price fluctuates based on raw material costs, size, and quantity. Please contact us with your specific requirements (diameter, length, quantity) for a real-time, competitive quotation.

3. What is the difference between 304 and 316 stainless steel bars?
316 contains Molybdenum, giving it significantly higher resistance to chlorides and acids. Choose 304 for general use; choose 316 for harsh environments like coastal areas or chemical processing.

4. What is your minimum order quantity (MOQ)?
Our standard MOQ is 1 ton. However, we can accommodate smaller trial orders for new clients. Please inquire for details.

5. Can you cut the bars to my specific length?
Yes, we offer precision cutting services. We can supply bars in random lengths, cut-to-length, or precisely machined to your drawings.

6. What surface finishes are available?
We supply bars in hot-rolled (HR), black, cold-drawn (CD), turned, and polished finishes to meet various application needs.

7. Do you offer free samples?
Yes, we provide free samples for quality verification. You are welcome to request a sample to test our material before placing a bulk order.

8. What are the lead times?
For standard sizes in stock, lead time is short. For large or custom orders, typical production time is 15-25 days after order confirmation.

9. What packaging do you use for export?
We use secure, export-worthy packaging with wooden crates and steel straps to prevent damage during international shipping. VCI anti-rust paper is also used for protection.

10. What payment terms do you accept?
We accept T/T (Telegraphic Transfer) and LC (Letter of Credit) at sight. Terms can be negotiated based on order value and history.

Additional Services

We provide value-added services including rough machining, heat treatment, cutting, machining, rolling, welding, and surface treatment to ensure your finished product is delivered ready for finishing. All forgings are rough machined according to your specifications and include Mill Test Reports (MTR), Mechanical and Physical Property Reports, as well as Ultrasonic, X-Ray, and Non-Destructive Testing (NDT) reports (as ordered or specified).
