Products Description
TP304 stainless steel pipe is an austenitic stainless steel pipe widely used in petrochemicals, food, construction, medicine, and heat exchange.
Features
Accurate size
We use the precision cold rolling process and strict dimensional tolerance control to ensure that the outer diameter and wall thickness of the stainless steel pipe are highly consistent, improve assembly efficiency, and reduce material waste and rework costs caused by errors.
Excellent corrosion resistance
The high chromium-nickel austenitic structure used in TP304 stainless steel pipe can form a self-passivating film on the surface, effectively resisting corrosion in acid, alkali, and hot and humid environments.
Weldability
The steel pipe adopts a low-carbon design and reasonably controls the nickel and chromium content to reduce the risk of intergranular corrosion and thermal cracking in the heat-affected zone of welding. It is suitable for TIG/MIG welding, which is convenient for on-site installation and complex structure docking.

FAQ
Q: What is TP304 stainless steel pipe commonly used for?
A: TP304 is widely used in industries such as chemical processing, food and beverage, pharmaceuticals, and architecture. Its excellent corrosion resistance and formability make it suitable for piping, heat exchangers, structural components, and sanitary applications.
Q: How does TP304 perform in corrosive environments?
A: Thanks to its high chromium (18%) and nickel (8%) content, TP304 forms a passive chromium oxide layer that resists oxidation and corrosion. It performs well in environments with mild acids and chlorides, though it's not ideal for highly concentrated or aggressive chloride conditions.
Q: Can TP304 stainless steel pipe be used at high or low temperatures?
A: Yes. TP304 maintains good mechanical integrity up to about 870°C and remains ductile and crack-resistant at cryogenic temperatures down to -196°C. This makes it suitable for both high-temperature and low-temperature applications.
Q: What are the mechanical properties of TP304 pipe?
A: TP304 offers a minimum tensile strength of 515 MPa and a minimum yield strength of 205 MPa. It typically achieves over 35% elongation, providing excellent formability and strength for various fabrication needs.
Q: Is TP304 pipe easy to weld?
A: Yes. TP304 is highly weldable using standard methods such as TIG, MIG, and plasma arc welding. It resists weld-related issues like hot cracking and usually doesn't require post-weld heat treatment, preserving both its mechanical and corrosion-resistant properties.
