Stainless Steel 304 pipes are widely used across industrial piping systems due to their excellent corrosion resistance, high strength, and outstanding fabrication properties. SS 304 is an austenitic chromium-nickel stainless steel that performs well in chemical processing environments, food grade applications, and structural piping systems.
Our SS 304 pipes are manufactured in compliance 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 traceability and quality assurance.
Stainless Steel 304 pipes are available in multiple grades including 304, 304L and 304H depending on application requirements such as corrosion resistance or high temperature performance. These pipes are produced according to international piping standards such as ASTM A312, ASTM A213, ASTM A269 and ASTM A778 ensuring dimensional accuracy and material reliability.
Our pipes are manufactured in sizes ranging from 1/8 inch NB to 30 inch NB with schedules from SCH 5 up to SCH XXS. Different manufacturing types including seamless, welded, ERW, EFW and LSAW are available to suit pressure piping systems, structural frameworks and process pipelines.

Stainless Steel 304 pipes derive their strength and corrosion resistance from their chromium and nickel content. Chromium forms a passive oxide layer that protects the steel from corrosion, while iron provides structural strength making SS 304 ideal for pressure piping systems, containers and process pipelines.
The balanced composition of chromium, nickel and carbon provides excellent mechanical properties including high tensile strength, good ductility and resistance to oxidation at elevated temperatures.

| Property | Value |
|---|---|
| Tensile Strength | 515 MPa |
| Yield Strength | 205 MPa |
| Elongation | 40 % |
| Hardness | 92 HRB max |
SS 304 pipes are manufactured using both seamless and welded production methods. Seamless pipes are produced through hot extrusion and cold drawing processes ensuring uniform strength and pressure resistance. Welded pipes are manufactured by rolling stainless steel plates or coils and welding them using automated processes such as TIG or laser welding.
After forming, pipes undergo heat treatment and finishing processes including annealing, pickling and polishing to improve corrosion resistance, durability and surface finish.
Quality assurance is maintained through comprehensive testing procedures including non-destructive testing methods such as ultrasonic testing (UT), radiographic testing (RT), magnetic particle inspection (MPI) and hydrostatic pressure testing. Mechanical testing such as tensile, bend, flattening and hardness tests are also performed to ensure compliance with ASTM specifications. Chemical composition verification is conducted using spectrometry to guarantee material accuracy and consistency.
All stainless steel 304 pipes are supplied with full documentation and certification to meet international project requirements. Quality management systems and inspection protocols ensure consistent performance and traceability across all batches.
SS 304 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 offer flexible delivery schedules and logistics support for both domestic and international shipments ensuring timely supply to project sites and industrial facilities worldwide.
