ASTM A269 is the core standard for seamless and welded austenitic stainless steel pipe for general service. It specifies requirements for chemical composition, heat treatment, mechanical properties, and dimensional tolerances. Due to its wide range of applications, from general fluid transport to structural uses, A269 has become one of the most frequently cited standards for general-purpose stainless steel pipe.

Austenitic stainless steel is the most widely used type, characterized by its non-magnetic nature, excellent toughness, outstanding cold formability, and good weldability. TP304L maintains excellent corrosion resistance even after welding due to its low carbon content, offering reliable rust protection and mechanical strength at a cost-effective price point.

Our seamless pipe undergoes rigorous cold working processes beginning with high-quality perforated billets. Multiple cold rolling or drawing steps reduce diameter and wall thickness while refining internal grain structure and surface finish. All pipes undergo solution annealing, pickling, passivation, and straightening to ensure required mechanical properties and corrosion resistance.

ASTM A269 TP304L seamless pipe serves diverse industrial needs including utility pipelines for water, gas, and oil in industrial plants, as well as structural applications like equipment frames and building railings. Its reliable performance and cost-effectiveness make it a foundational material for manufacturing, construction, and processing industries.
