Emirerri Steel supplies ASTM A333 / SA333 Gr 11 low-temp alloy steel pipes, OD 1/8''–36'', wall 2–14 mm, seamless & welded for LNG, cryogeni
ASTM A333 / SA333 Grade 11 is an alloy steel pipe specification designed for low-temperature service where high impact toughness and reliability are required. The ASTM A333 standard covers both seamless and welded carbon and alloy steel pipes intended for use in cryogenic and cold-environment applications. These pipes are manufactured with controlled chemical composition and heat treatment processes to ensure strong mechanical performance even at sub-zero temperatures.
ASTM A333 Grade 11 pipes are known for their excellent resistance to brittle fracture and improved durability in cold climates. The material composition typically includes low carbon content along with elements such as nickel, chromium, and molybdenum, which enhance strength, toughness, and corrosion resistance. The grade contains up to 0.10% carbon, about 0.60% manganese, and controlled levels of alloying elements that contribute to its mechanical stability in extreme environments.
