Product Description

Discover the exceptional durability and performance of our Stainless Steel Plate 304L, Heat Resistant. This premium austenitic stainless steel plate is specifically engineered to maintain its structural integrity, corrosion resistance, and strength in high-temperature environments up to 870°C (1598°F). The 304L heat resistant plate is an ideal solution for industries requiring reliable performance under thermal stress, offering superior oxidation resistance and long-term stability.

Product Information

The Stainless Steel 304L Heat Resistant Plate is a low-carbon variation of the classic 304 grade. The reduced carbon content minimizes carbide precipitation during welding and high-temperature exposure, ensuring excellent intergranular corrosion resistance. This plate is supplied in a hot-rolled or cold-rolled finish, with thickness and dimensions tailored to withstand sustained thermal cycling and elevated operating conditions.

Key Characteristics & Selling Points

•
High-Temperature Resilience: Performs reliably in intermittent service up to 870°C and continuous service up to 815°C.
•
Enhanced Corrosion Resistance: The low carbon content provides superior resistance to sensitization and intergranular corrosion in welded structures and high-temperature applications.
•
Excellent Oxidation Resistance: Forms a stable, protective chromium oxide layer that prevents scaling and maintains surface quality under heat.
•
Outstanding Formability & Weldability: Offers good ductility and can be readily welded and fabricated using all standard methods, without the need for post-weld annealing.
•
Strength & Toughness: Maintains high mechanical strength and good toughness across a wide temperature range.

Applications & Usage

The 304L heat resistant plate is extensively used in manufacturing components that operate in elevated temperature environments. Common applications include:

•
Heat Exchangers, Boilers, and Thermal Oil Systems
•
Furnace Parts, Heat Treatment Baskets, and Kiln Linings
•
Exhaust Systems and Automotive Manifolds
•
Chemical Processing Equipment exposed to moderate heat
•
Food Processing and Brewery Equipment requiring heat and corrosion resistance

Production & Technology

Our 304L heat resistant plates are produced using advanced electric arc furnace (EAF) melting, often coupled with Argon Oxygen Decarburization (AOD) refining. This technology ensures precise control over the chemical composition, particularly the low carbon and balanced chromium-nickel ratio, which is critical for high-temperature performance. The plates undergo controlled hot-rolling and specific heat treatment processes to achieve the desired metallurgical structure, grain size, and mechanical properties optimized for thermal stability.

Advantages Over Alternatives

Choosing our 304L Heat Resistant Plate provides distinct benefits. Compared to standard 304 plates, it offers significantly better weldability and resistance to intergranular attack in high-temperature service, extending component lifespan. Versus higher-grade heat-resistant alloys, it provides a more cost-effective solution for a wide range of moderate to high-temperature applications without compromising on essential corrosion resistance or fabricability.

Service Commitment

We provide comprehensive technical support, from material selection guidance for your specific operating temperatures to detailed Mill Test Certificates (MTCs) ensuring traceability and compliance with international standards. Custom cutting and sizing services are available to meet your precise fabrication requirements.

FAQ

•
Q: What is the main difference between 304 and 304L heat resistant plates?

A: The key difference is the carbon content. 304L has a maximum 0.03% carbon, reducing the risk of carbide precipitation during welding or high-temperature exposure, which is crucial for heat-resistant applications.
•
Q: Can the Stainless Steel 304L Plate be used for food processing applications involving heat?

A: Yes, its combination of corrosion resistance, cleanability, and heat resistance makes it suitable for various food processing, cooking, and brewery equipment components.
•
Q: How does this plate perform in cyclic heating and cooling conditions?

A: The 304L grade exhibits good resistance to thermal fatigue and oxidation under cyclic conditions, making it suitable for applications involving repeated thermal cycling.
