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.
The addition of copper to this grade gives it corrosion resistant
properties superior to the conventional chrome nickel stainless
steels, in particular to sulphuric, phosphoric and acetic acids.
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.
The grade is non-magnetic in all conditions and has excellent
formability and weldability. The austenitic structure also gives
this grade excellent toughness, even down to cryogenic
temperatures.
The high chromium content promotes and maintains a passive film
which protects the material in many corrosive environments.904L has
a greater resistance to precipitation of ferrite and sigma phases
on cooling and welding than other stainless steels containing
molybdenum such as 316L and 317L. There is no risk of
intercrystalline corrosion on cooling or welding due to the low
carbon content. Its maximum service temperature is at 450°C.
This grade is particularly useful in control and instrumentation
tubing applications where 316 and 317L are not suitable.
