ALLOY 904L • UNS N08904 • WNR 1.4539

Applications of SS 904 / 904L Alloy Steel / N08904 /AISI 904L Pipes & Tubes:

Alloy 904 & 904L (N08904) Stainless Steel Pipe, Tube, Fittings and Flanges are used in the chemical industry to process corrosive chemicals such as: Acetic acid, Acetylene, Acrylates, Acrylonitrile, Aluminum sulfate, Ammonium phosphate, Ammonium sulfate, Battery acid, Benzene, Butyl acetate, Caprolactum, Cellophane, Citric acid, Nitro phosphate, Oxalic acid, Superphosphate, Tall oil, Tartaric acid, Uranium oxide and Zinc sulfate.

Properties of SS 904 / 904L Alloy Steel / N08904 /AISI 904L Pipes & Tubes:

Alloy 904 / N08904 Stainless Steel is a high alloy austenitic product intended for use under severely corrosive conditions. It offers good resistance to:

  • Pitting and crevice corrosion
  • Intergranular corrosion
  • Stress corrosion cracking
  • General corrosion

Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless steel has added copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. Grade 904L stainless steel is non-magnetic, and offers excellent formability, toughness and weldability. Grade 904L contains high amounts of expensive ingredients, such as molybdenum and nickel. Today, most of the applications that employ grade 904L are replaced by low-cost duplex stainless steel 2205.

Grade 904L stainless steels have excellent resistance to warm seawater and chloride attack. The high resistance of grade 904L against stress corrosion cracking is due to the presence of high amounts of nickel in its composition. Moreover, the addition of copper to these grades develops resistance to sulphuric acid and other reducing agents in both aggressive and mild conditions.

The corrosion resistance of grade 904L is intermediate between super austenitic grades, with 6% molybdenum content and standard 316L austenitic grades. Grade 904L is less resistant to nitric acid than grades 304L and 310L, which are free of molybdenum. This steel grade needs to be solution treated following cold working, to achieve maximum stress corrosion cracking resistance under critical environments.

UNS NO8904, commonly known as 904L, is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of AISI 316L and AISI 317L are not adequate.
However, there is limited use with hydrochloric acids. It also has a high resistance to pitting in chloride solutions, a high resistance to both crevice and stress corrosion cracking. Alloy 904L performs better than other austenitic stainless steels due to the higher alloying of nickel and molybdenum.This grade is particularly useful in control and instrumentation tubing applications where 316 and 317L are not suitable.
