Alloy steel welded pipes consist of additives such as chromium, molybdenum, nickel, manganese, and carbon, which improve their mechanical properties and heat and corrosion resistance. Typical grades like ASTM A335 P11, P22, and P91 have tensile strength in the range of 415–620 MPa and yield strength in the range of 205–380 MPa, with elongation generally in excess of 20%. These pipes retain high toughness and hardness as well, hence being appropriate for high-temperature and high-pressure situations, and providing long service life along with structural strength in harsh industrial conditions.
