ASTM A312 TP304L / UNS S30403 Stainless Steel For Chemical Industry
ASTM A312 TP304L is a specification for seamless， welded， and heavily cold worked austenitic stainless steel pipes. TP304L specifically refers to the low carbon version of TP304 stainless steel. These pipes are commonly used in industries such as chemical， petrochemical， food processing， and more， where corrosion resistance is crucial. We， TONG CHUANG GROUP have abundant manufacturing experience of ASTM A312 stainless steel pipes for more than 30 years.
Key Features and Specifications:
Material: TP304L is an austenitic stainless steel with low carbon content， which helps to prevent sensitization during welding and maintains excellent corrosion resistance.
Size Range: The pipes covered by ASTM A312 TP304L come in a variety of sizes， ranging from 1/8" to 24" (DN6 to DN600).
Wall Thickness: The wall thickness of TP304L pipes varies and is specified in the standard.
Types: The pipes can be either seamless or welded. The "L" in TP304L indicates that the material has a low carbon content.
Heat Treatment: The pipes are generally solution annealed after welding to restore the material's corrosion resistance and mechanical properties.
Applications: These pipes are commonly used in applications where corrosion resistance is essential， such as in the chemical processing， food processing， pharmaceutical， and oil and gas industries.
Testing and Inspection: ASTM A312 TP304L requires certain mechanical property testing， such as tensile strength， yield strength， and elongation. Other tests include hydrostatic or nondestructive electric tests.
