Stainless Steel 304H Plates
At ASC LLP, we pride ourselves on delivering top-quality materials to meet the diverse needs of our clients. Among our extensive range of products, 304H stainless steel plates stand out due to their exceptional performance and durability. In this article, we will explore what 304H stainless steel plates are, their properties, material composition, and the advantages they offer.
What is 304H Stainless Steel Plates?
304H stainless steel plates are a high-carbon version of the 304 stainless steel grade, designed for high-temperature service. The increased carbon content (between 0.04% and 0.10%) enhances its strength and heat resistance, making it an ideal choice for applications requiring robustness at elevated temperatures.

Properties of 304H Stainless Steel Plates
The unique composition of 304H stainless steel plates endows them with several beneficial properties:
- High Strength and Durability: The elevated carbon content provides increased tensile and yield strength, ensuring the plates can withstand significant mechanical stress.
- Excellent Corrosion Resistance: Like other 304 stainless steel grades, 304H offers excellent resistance to a wide range of corrosive environments, including oxidizing and reducing agents.
- Superior Heat Resistance: With a higher carbon content, 304H plates maintain strength and stability at temperatures up to 800°C (1472°F), making them suitable for high-temperature applications.
- Good Weldability: Despite the higher carbon content, 304H stainless steel plates retain good weldability and can be welded using standard techniques.
Advantages of Using 304H Stainless Steel Plates
Choosing 304H stainless steel plates from ASC LLP offers several advantages for industrial and commercial applications:
- Enhanced High-Temperature Performance: The ability to retain strength and stability at elevated temperatures makes 304H plates ideal for use in heat exchangers, boilers, and other high-temperature environments.
- Versatility: Suitable for a variety of applications, from chemical processing equipment to power generation, due to their robust properties and resistance to corrosion.
- Cost-Effective: Despite their superior performance, 304H stainless steel plates offer a cost-effective solution compared to other high-performance alloys.
- Longevity: The durability and resistance to wear and tear ensure a long service life, reducing the need for frequent replacements and maintenance.
