304H stainless steel pipe is a stainless steel pipe material with a high carbon content, mainly used for applications in high temperature and corrosive environments.

Chemical composition and performance characteristics

The main chemical components of 304H stainless steel pipe include carbon (C), chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), phosphorus (P) and sulfur (S). Its high carbon content, usually between 0.04% and 0.10%, gives it higher strength at high temperatures. The content of other elements such as chromium (18.00%-20.00%) and nickel (8.00%-11.00%) ensures its good corrosion resistance. Although the corrosion resistance of 304H is not as good as 304L in resisting intergranular corrosion, its corrosion resistance in high temperature and acidic environment is still excellent.

Application field

Due to its high temperature strength and corrosion resistance, 304H stainless steel pipe is widely used in the following fields:

High temperature equipment: such as high temperature furnaces, burners, petrochemical equipment, etc.

Heat exchanger: used to manufacture heat exchangers that require high temperature resistance and corrosion resistance.

Pharmaceutical equipment: 304H stainless steel is often used in situations that require high cleanliness and corrosion resistance.
