H in 304H refers to high temperature, and high carbon content is the guarantee of high temperature strength. When GB150 requires austenite steel to be used above 525 degrees, the carbon content is not less than 0.04%, and the carbide is the strengthening phase, especially the high temperature strength Better than pure austenite. The higher the carbon content, the worse the corrosion resistance of stainless steel and the easier it is to rust. High temperature performance is better than 304 stainless steel.
