ASTM A335 / ASME SA335 P22 Alloy Steel Seamless Pipe 2.25Cr-1Mo Steel Pipe
ASTM A335 P22 is a type of alloy steel pipe that is designed for high-temperature and high-pressure applications. It is made from a combination of chromium, molybdenum, and other elements, which gives it excellent corrosion resistance and high-temperature strength. Here are some key features and properties of A335 P22 pipes:
