ASTM A335 P9 Alloy Steel Seamless Pipe
ASTM A 335 P9 alloy pipe is manufactured using high-quality raw materials from reliable and trustworthy suppliers in the industry. These products undergo various heat treatments and testing procedures such as impact test, hydrostatic test, tensile test and non-destructive electrical test to verify whether they meet the specified characteristics.
ASTM A 335 P9 is a seamless ferritic chromium-molybdenum alloy pipe for high temperature service. A 335 P9 seamless pipe has a chromium content of 10.00%, a molybdenum content of 1.10%, a minimum tensile strength of 415MPa, and a minimum yield strength of 205Mpa. Because ASTM A 335 P9 alloy steel pipe contains high levels of chromium and molybdenum, it is also called chrome-molybdenum pipe.
ASTM A335 P9 chrome-molybdenum pipe is designed for high temperature service and has good corrosion resistance, which are its two main advantages. Therefore, ASTM A 335 P9 high temperature pipe is mainly used in boilers, chemical industry, power, petroleum, oil and gas, etc.
