ASTM A53 Gr.B Black and hot-dipped zinc-coated steel pipes welded and seamless

ASTM A53 Gr.B high-temperature carbon steel pipe is a high-performance tubing manufactured in compliance with ASTM A53/A53M standards, specifically designed for high-temperature fluid transportation applications. Its chemical composition is meticulously formulated with a carbon content ≤0.30%, manganese content ranging from 0.29% to 1.06%, phosphorus and sulfur content each ≤0.035%, and silicon content ≥0.10%. This composition design endows the steel pipe with excellent mechanical properties: tensile strength ≥415 MPa, yield strength ≥240 MPa, and elongation meeting standard requirements, ensuring structural stability even under high-temperature and high-pressure operating conditions.
