ASTM A213 / ASME SA213 TP304L Stainless Steel Seamless Tube
概述
ASTM A213 TP304L is a specification for austenitic stainless steel seamless tubing. Specifically， TP304L is a low carbon content stainless steel material whose chemical composition consists primarily of chromium (Cr) and nickel (Ni)， with small amounts of carbon (C) and other alloying elements.
ASTM A213 is a standard specification for seamless alloy steel and stainless steel pipe developed by the American Society for Testing and Materials (ASTM). The specification specifies the chemical composition， mechanical properties， heat treatment requirements， dimensions， and other requirements for piping materials.
Therefore， ASTM A213 TP304L specification is applicable to industries related to the production and use of low carbon content austenitic stainless steel TP304L pipe， such as chemical， oil and gas， food processing and other fields. It has good corrosion resistance and weldability and performs well in high temperature and corrosive environments.
