304H Stainless Steel Strip for High-Temperature Applications

TISCO Steel Group (Jiangsu) Co., Limited is your trusted partner for premium stainless steel products. As a leading supplier, we are authorized to distribute high-quality materials from renowned mills including TISCO, Tsingshan, BAOSTEEL, and ANSTEEL. This ensures that every coil of 304H Stainless Steel Strip we provide comes with guaranteed traceability, exceptional consistency, and mill test certificates that comply with the most stringent international standards.

304H is the high-carbon version of the classic 304 alloy. The elevated carbon content enhances its strength and, most importantly, its resistance to sensitization ( carbide precipitation) in the critical temperature range of 800°F – 1500°F (425°C – 815°C). This makes 304H strip an ideal choice for high-temperature applications such as heat exchanger components, furnace parts, pressure vessels, and boiler systems in the chemical processing, power generation, and oil & gas industries.

Our 304H strip offers key advantages:

  • Excellent High-Temperature Strength: Maintains structural integrity under sustained thermal stress.

  • Superior Corrosion Resistance: Offers the same good general corrosion resistance as 304.

  • Readily Fabricable: Can be readily formed and welded using standard techniques.

A key consideration is that it is not recommended for use in highly corrosive environments in the as-welded condition, as the heat-affected zone may be susceptible to corrosion.

We provide custom slitting services to deliver strips in precise widths and tolerances to optimize your production efficiency. Our team offers expert technical support to help you select the right material for your project, ensuring performance and cost-effectiveness.

FAQ

1. What is the main difference between 304 and 304H?
The key difference is the carbon content. 304H has a higher carbon content (0.04-0.10%) than regular 304, which gives it improved high-temperature strength.

2. Can 304H be used for welding?
Yes, it can be welded by all standard methods. However, for applications in corrosive environments post-welding, a solution annealing treatment may be necessary to restore maximum corrosion resistance.

3. What is the maximum service temperature for 304H?
It can be used in intermittent service up to 1600°F (870°C) and continuous service up to 1690°F (920°C).

4. Do you provide full material certification?
Yes, we supply a complete Mill Test Certificate (MTC) with every order, traceable to the original mill (TISCO, BAOSTEEL, etc.), verifying chemical composition and mechanical properties.

5. What surface finishes are available?
We supply 304H strip in 2B, BA (Bright Annealed), No.4 (Brushed), and Hairline finishes.

6. Can you custom-slit the strips to my specific width?
Absolutely. We specialize in precision slitting and can provide strips in custom widths to your exact specifications, minimizing your processing time.

7. What is your minimum order quantity (MOQ)?
Our standard MOQ is 1 ton, but we can accommodate smaller trial orders for new partnerships.

8. How does the price of 304H compare to 304?
304H typically carries a slight price premium due to its controlled composition and specialized high-temperature properties.

9. What industries commonly use 304H strip?
It is widely used in power plants, chemical processing facilities, oil refineries, and for manufacturing heat exchangers and fired heater tubes.

10. How do I request a sample?
Simply contact us with your request. We offer free samples of our 304H strip so you can verify quality before placing a full order.

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.
