ASTM A333 Grade 4 is the part of standard covers wall seamless and
welded carbon and alloy steel pipe intended for use at low
temperatures. ASTM A333 Grade 4 alloy pipe shall be made by the
seamless or welding process with the addition of no filler metal in
the welding operation.
ASMT A333 Grade 4 seamless and welded pipes
ASMT A333 Grade 4 seamless and welded pipes shall be treated to
control their microstructure. Tensile tests, impact tests,
hydrostatic tests, and nondestructive electric tests shall be made
in accordance to specified requirements.
