Stainless Steel 304L pipes are widely used across industrial piping systems where corrosion resistance and weldability are critical. SS 304L is the low carbon version of SS 304 which helps prevent carbide precipitation during welding and improves corrosion resistance in welded structures.
Our SS 304L pipes are manufactured in accordance with international standards such as ASTM and ASME specifications and are available in seamless, welded and ERW forms. Each pipe is supplied with mill test certificates ensuring material traceability and quality assurance.
Stainless Steel 304L pipes are produced in accordance with ASTM A312, ASTM A213, ASTM A269 and ASTM A778 standards ensuring high dimensional accuracy and reliable mechanical performance. The low carbon content improves weldability and minimizes the risk of intergranular corrosion.
These pipes are available in sizes ranging from 1/8 inch NB to 30 inch NB with schedules from SCH 5 up to SCH XXS. Various manufacturing methods including seamless, welded, ERW, EFW and LSAW are available to suit different industrial piping requirements.

SS 304L pipes contain chromium and nickel which provide excellent corrosion resistance and oxidation stability. Chromium forms a passive oxide layer protecting the surface from corrosion while iron provides the structural strength required for industrial piping systems.
The low carbon content in SS 304L helps prevent sensitization during welding which makes the material suitable for applications where post-weld corrosion resistance is critical.

SS 304L pipes are manufactured using both seamless and welded production methods. Seamless pipes are produced through hot extrusion and cold drawing processes which ensure uniform strength and pressure resistance. Welded pipes are produced by forming stainless steel coils and joining them using automated welding processes.
Following fabrication, pipes undergo heat treatment, pickling and surface finishing processes to improve corrosion resistance and ensure smooth surface quality.
Quality assurance includes non-destructive testing methods such as ultrasonic testing (UT), radiographic testing (RT), magnetic particle inspection (MPI) and hydrostatic testing. Mechanical testing including tensile, bend, flattening and hardness tests ensures compliance with ASTM specifications.
All SS 304L pipes are supplied with complete quality documentation ensuring compliance with international industry standards.
SS 304L pipes are packed using export grade wooden crates, bundles or protective wrapping to prevent damage during transportation. Each shipment includes complete documentation and marking for easy identification.
We provide flexible delivery timelines and logistics support for both domestic and international shipments ensuring timely supply to industrial facilities worldwide.
