ASTM A333 Gr.6 Seamless Alloy Pipe For Large Industrial Refrigeration Systems
ASTM A333 Gr.6 Seamless Alloy Pipe For Large Industrial Refrigeration Systems
A333 This specification covers nominal (average) wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures.Its primary function is to provide excellent notch toughness and prevent brittle fracture in environments where standard carbon steel would fail.
