A M Industries proudly offer a superior range of strong, Stainless Steel 904L Pipes Manufacturers to a wide array of industrial applications. Stainless Steel 904L is high-performance, non-stabilized austenitic steel with low carbon content.The highly characteristic composition, with a high concentration of nickel and molybdenum with additions of copper, guarantees extraordinary resistance to corrosion and reducing acids, especially in more extreme applications. This resistant material also displays very good resistance against stress corrosion cracking, pitting, and carburization for long service life in the most difficult conditions.

Our suppliers of Stainless Steel 904L Pipes offer them in different sizes, shapes, and schedules to meet the varying requirements of our customers. Available from 1/8-24 nominal and outer diameter between ¼mm - 24mm, these pipes can be availed in lengths up to 30 meters. Our products feature 7.95 g/cm³ density and their melting point at 1350°C in conformity with global standards. It has superior property, so they are in demand from high-tech industries ranging from aerospace and petrochemical engineering to the pharmaceutical industry, whereby traditional grades, such as types 316L and 317L, cannot make a sufficient level of accomplishment.

SS 904L Welded Pipe is preferred due to the low content of carbon in it, which eventually makes the production process pretty easy. It represents improved mechanical properties and a higher degree of resistance to corrosion from more general applications of welded pipes. ASTM B673 UNS N08904 pipes range in diameters from 5mm to 1219.2mm, with wall thickness in a range from 0.5mm to 20mm. Seamless types manufactured from single sheets of steel are available from the stockiest of Stainless Steel 904L Pipes meant for applications that require a bit more strength.

Seamless tubes from this material grade DIN 1.4539 are represented for excellent structural strength, outer diameter sizes ranging from 4mm to 219mm with similar thickness ranges. Seamless and welded pipes serve different purposes. Seamless types are usually used where the pressure usage is high, while economic benefits are derived from the welded type without compromising quality. Both grade types have minimum tensile strengths of 490 MPa and yield strengths of 220 MPa, with excellent elongation properties.

Versatility is an added virtue at A M Industries. The addition of copper to this Stainless Steel Grade 1.4539 increases its resistance to corrosion manifold. Tubing and piping are manufactured in line with specific requirements. Therefore, ASTM A312 TP 904L Round Pipe is the resultant product of great strength finds wide application in structural construction and transportation of fluids both. The square pipes, for instance, the SA 312 TP 904L, are cold-rolled to impart on them a refined finish to assist in corrosion resistance. Likewise, the rectangular pipes, such as the AISI 904L, are precision welded to meet specific demands set forth by the industry.

Our products extend their serviceability for a wide range of pressure and temperature applications. A good example could be the 904L 1.4539 Schedule 40 Pipe, which, for example, is intended for operation at both low and high pressures at temperatures up to 140°F. Their versatility means they can serve in industries that demand strong, reliable performance under variable conditions.
