Main ingredients:

All three materials have chromium (Cr) and nickel (Ni) as the main alloying elements, of which:

1. The chromium content is usually between 18-20%.

2. The nickel content is usually between 8-11%.

Application fields:

TP304, TP304H, and TP304L are widely used in petroleum, chemical, food processing, medicine, and other industrial fields for conveying corrosive media, high temperature and high-pressure fluids, etc.

The difference between TP304, TP304L, and TP304H stainless steel pipes:

ASTM A213 TP304 stainless steel pipe:

Composition: TP304 is a common austenitic stainless steel, the main components of which are 18-20% chromium (Cr) and 8-11% nickel (Ni).

Features: It has good corrosion resistance, processability, and weldability, and is suitable for general industrial applications.

ASTM A213 TP304L stainless steel pipe:

Composition: TP304L is low-carbon stainless steel with a low carbon content, which helps to reduce the tendency of carburization during welding.

Features: Compared with TP304, TP304L has better welding performance and corrosion resistance, and is more stable in low-temperature environments.

ASTM A213 TP304H stainless steel pipe:

Composition: TP304H is a high-carbon stainless steel with a high carbon content, which helps to improve strength at high temperatures.

Features: Suitable for high-temperature applications, with excellent heat resistance and strength, and performs better in high-temperature environments.

Summary of the main differences:

1. TP304 is a standard stainless steel suitable for general applications.

2. TP304L has better welding performance and stability in low-temperature environments.

3. TP304H is suitable for high-temperature environments and has higher heat resistance and strength.
