SS 904L Pipes for Demanding Industrial Applications
SS 904L / UNS N08904 Pipes provide excellent corrosion resistance in demanding industrial environments. Their chromium, nickel, molybdenum and copper composition helps resist pitting, crevice corrosion, chloride attack and aggressive acids.
These pipes are suitable for chemical processing, marine, offshore, pharmaceutical, and power applications where reliable corrosion resistance, durability, and long-term performance are essential.
Our Stainless Steel 904L Pipes are produced from a high-alloy, low-carbon austenitic stainless steel developed for applications where excellent corrosion resistance and long-term durability are essential. The addition of nickel, molybdenum, and copper provides superior resistance to pitting, crevice corrosion, and reducing acids, making 904L Pipes an ideal choice for harsh operating environments.
We manufacture and supply a complete range of 904L Seamless Pipes, 904L Welded Pipes, and 904L ERW Pipes suitable for industrial piping systems, fluid transportation, structural applications, and process equipment. Available in standard as well as custom dimensions, our pipes are engineered to meet the performance requirements of a wide range of industries.
Our SS 904L Pipes are designed to deliver dependable performance in challenging industrial applications.

Frequently Asked Questions (FAQ)
What types of 904L Pipes do you offer?
We offer a complete range of 904L Pipes, including 904L Seamless Pipes, 904L Welded Pipes, 904L ERW Pipes, and fabricated piping solutions for industrial applications.
What is the difference between a 904L Seamless Pipe and a 904L Welded Pipe?
A 904L Seamless Pipe is manufactured without a welded joint, making it suitable for high-pressure and critical process applications. A 904L Welded Pipe is produced by welding stainless steel plates or coils and is widely used for general industrial piping systems. 904L ERW Pipes are manufactured using electric resistance welding and provide excellent dimensional accuracy and cost-effective performance.
What pipe sizes are available?
Our Stainless Steel 904L Pipes are available from 1/2″ NB to 12″ NB in seamless construction and 2″ NB to 36″ NB in welded construction, with customized sizes available upon request.
Can you manufacture custom 904L Pipes?
Yes. We manufacture Custom 904L Pipes in various diameters, wall thicknesses, schedules, and lengths according to customer specifications and project requirements.
What industries commonly use SS 904L Pipes?
SS 904L Pipes are widely used in chemical processing, petrochemical plants, oil & gas, marine, power generation, fertilizer, desalination, pharmaceutical, and food processing industries where superior corrosion resistance is essential.
Are test certificates supplied with the material?
Yes. Every shipment can be supplied with a Manufacturer Test Certificate, including EN 10204 3.1 / 3.2 documentation where required, ensuring complete material traceability and quality assurance.
