What is Carbon Steel A672 Gr CC 70 Pipe?

Carbon Steel A672 Gr CC 70 Pipe is made from carbon-manganese steel plates, featuring a typical chemical composition that includes carbon (up to 0.30%), manganese (0.60–1.35%), phosphorus (maximum 0.035%), and sulfur (maximum 0.040%). This pipe type delivers outstanding mechanical strength, with a minimum yield strength of 260 MPa and tensile strength ranging from 485 to 620 MPa. Designed for moderate to high-temperature service, these EFW pipes provide excellent weldability, impact resistance, and a long service life. Grade CC 70 is particularly recognized for its toughness, pressure resistance, and reliable performance under thermal and mechanical stress.
