ASTM A333Gr.6 steel pipe chemical composition:
Carbon: ≤0.30, Silicon: ≥0.10, Manganese: 0.29~1.06, Phosphorus: ≤0.025, Sulfur: ≤0.025, Chromium: ≤0.030, Nickel: ≤0.040, Molybdenum: ≤0.12, Copper: ≤0.40, Vanadium: ≤0.08, Niobium; ≤0.02.
Based on agreement, the niobium content may be increased to 0.05% for heat analysis and 0.06% for finished product analysis.
Mechanical properties of ASTM A333 Gr.6 Carbon Steel Seamless Pipes:
Tensile strength: minimum 415 MPa,
Yield strength: minimum 240 MPa,
Elongation: minimum 30%,
Commonly used: Impact test temperature -45℃,
The above requirements can ensure the normal use of the pipeline in low temperature environment, with sufficient strength and toughness.
Product specifications: outer diameter 21.3mm~762mm, wall thickness 2.0mm~140mm
