Stainless Steel 904L Seamless Pipe Manufacturer

Mcneil Instrument offers 904L Stainless Steel Pipes, which are characterized by their highly alloyed composition, low carbon content, and non-stabilized austenitic structure. These pipes are specifically designed to resist strong reducing acids such as sulfuric acid due to the addition of copper in the alloy. With a lower carbon content, Mcneil Instrument ensures that the AISI 904L Welded Pipes are manufactured according to ASTM A312 specifications, allowing them to be suitable for high temperature applications. The inclusion of nickel in the ASME SA 312 TP904L alloy enhances the pipes’ performance even in elevated environments. Additionally, the non-magnetic nature of Stainless Steel 904L Pipes, coupled with their resistance to stress-related corrosion cracking, makes them highly reliable. The presence of molybdenum further reduces the risk of crevice corrosion, making ASTM A312 TP904L pipes ideal for a wide range of general corrosion applications.

Mcneil Instrument conducts mechanical tests such as transverse or longitudinal tension tests and flattening tests to ensure conformance to the required tensile properties of the 904L Seamless Pipes. Adhering to ASTM A312 standards, each Mcneil Instrument 904L Pipe is furnished in a heat-treated condition, with precise temperature control and cooling procedures to meet stringent quality requirements.
