Aman Pipes and Tubes, a Hyderabad, India-based company, is a reliable manufacturer and exporter of Stainless Steel 904L Seamless Pipes to various industrial segments around the world. With our reputation for accuracy engineering, quality control, and customer-focused services, we provide an extensive array of seamless pipes specifically designed to suit highly corrosive applications. Our SS 904L seamless tubes are produced with the latest technology and high-grade raw materials, which guarantee high durability, strength, and performance. We supply these to chemical processing, pharmaceutical, power generation, and marine industries, and adhere strictly to international standards with a delivery schedule ensured on time.
Stainless Steel 904L Seamless Tubes consist mainly of iron, with small percentages of chromium (19-23%), nickel (23-28%), molybdenum (4-5%), and copper (1-2%) for added corrosion resistance. These pipes have very good mechanical properties, such as minimum tensile strength of 490 MPa and minimum yield strength of 220 MPa. The elongation at break is generally 35% or greater, and they possess better toughness even at cryogenic temperatures. The low carbon content in the material also improves weldability and minimizes the chances of intergranular corrosion, thus making it exceptionally fit for corrosive and aggressive environments.

904L Stainless Steel Seamless Pipes have vast applications in industries that demand exceptional corrosion resistance and structural stability. Their uses include oil and gas, petrochemical, chemical processing, marine engineering fields, where they can resist aggressive chemicals, sulfuric acid, and chloride-containing environments. They are used in heat exchangers, pressure vessels, condenser tubing, and anti-pollution equipment, too. Their high formability, strength, and resistance to pitting and crevice corrosion render them suitable for application in high-temperature and high-pressure systems to provide long service life and reliable operation.
