ASTM A312 TP321 Stainless Steel Seamless Pipe Pickling Anealed Oil Gas Industry and Chemical Industry Application
ASTM A312 TP321 stainless steel pipe is a high-performance, multi-purpose stainless steel pipe widely used in multiple industrial fields. There are various specifications for pipes, usually ranging from 6mm to several hundred millimeters in outer diameter, and a wide range of wall thickness. Its production follows the ASTM A312 standard, ensuring that the quality and performance of the product meet international requirements.
ASTM A312 TP321 pipes are mainly composed of chromium (Cr), nickel (Ni), and a small amount of titanium (Ti) elements. The addition of these elements endows the tube with unique properties:

ASTM A312 TP321 pipes can maintain good corrosion resistance in various harsh environments such as high temperature and high pressure, including corrosive media such as acid, alkali, salt, etc; High nickel content can enable TP321 pipes to maintain high strength and toughness under high temperature conditions; At the same time, the addition of titanium element makes the TP321 pipes less prone to cracking and embrittlement during the welding process, making it easy to process and weld, ensuring the quality and reliability of the welded joint; The austenitic structure endows the pipe with excellent mechanical properties, possessing sufficient strength to withstand working pressure and good toughness.
