304H stainless steel is a high-carbon variant of 304 stainless steel, designed to deliver enhanced strength and durability at elevated temperatures. This makes it a popular choice for industries such as petrochemical, power generation, and heat treatment equipment manufacturing.
The higher carbon content in 304H improves its tensile strength and creep resistance, making it suitable for long-term exposure to temperatures above 500°C. It also retains excellent corrosion resistance, making it ideal for harsh environments.
