ASTM A335 Grade P22 Alloy Steel Seamless Pipes

ASTM A335 Grade P22 Alloy Steel Seamless Pipes are Carbon Steel Pipes with subsequent addition of chromium, molybdenum and sometimes vanadium are known as chrome moly Pipes. ASTM Specification alloy steel Pipes are used for high temperature service applications. Seamless Alloy Steel Pipes according to ASTM A335 Grade P22 are reheated and furnished in full annlealed,isothermal annealed or normalised quenched and tempered condition. ASTM A335 Grade P22 Alloy Steel Seamless Pipes have a typical chemistry with additions of 1.90-2.60 Chromium and 0.87-1.13 Molybdenum. Bearing minimum tensile strength of 415 Mpa ASTM A335 Grade P22 Pipes have a minimum yield strength of 205 Mpa.
