Useful Information:
904L is a low carbon high alloy austenitic stainless steel, with an chromium, nickel, molybdenum and copper content, which is widely used in applications where the corrosion properties of 316L & 317L are not adequate. although originally develop for greatly improved resistance to strong reducing acids, particularly sulphuric acid. It also has an very high resistance to a wide range of environments. This feature has been verified that it is very successful after many years of practical applications, which has results that 904L has been standardized in many countries.
904L is a non-stabilised low carbon high alloy austenitic stainless steel. The addition of copper to this grade gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid. It is also highly resistant to chloride attack – both pitting / crevice corrosion and stress corrosion cracking. This grade is non-magnetic in all conditions and has excellent weldability and formability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures. 904L does have very substantial contents of the high cost ingredients nickel and molybdenum. Many of the applications in which this grade has previously performed well can now be fulfilled at lower cost by duplex stainless steel 2205 (S31803 or S32205), so it is used less commonly than in the past.
Characteristics
- The high Mo and the addition of copper to this grade gives it greatly improved resistance to strong reducing acids, particularly aspheric acid
- It is highly resistant to chloride attack, both pitting crevice corrosion and stress corrosion crashing
- Good machine ability and weld ability
- The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures
Market applications:
- Offshore, oil & gas
- Chemical processes
- Seawater cooling equipment
- Control and instrumentation
- Pharmaceutical
- Pulp and paper processing

Possible alternative grades to 904L stainless steel.
| Grade |
Why it might be chosen instead of 904L |
|
316L |
A lower cost alternative, but with much lower corrosion resistance. |
|
6Mo |
A higher resistance to pitting and crevice corrosion resistance is needed. |
|
2205 |
A very similar corrosion resistance, with the 2205 having higher mechanical strength, and at a lower cost to 904L. (2205 not suitable for temperatures above 300°C.) |
|
Super duplex |
Higher corrosion resistance is needed, together with a higher strength than 904L. |
Heat Resistance
Good resistance to oxidation, but like other highly alloyed grades suffers from structural instability (precipitation of brittle phases such as sigma) at elevated temperatures. 904L should not be used above about 400°C.
Heat Treatment
Solution Treatment (Annealing) – heat to 1090-1175°C and cool rapidly. This grade cannot be hardened by thermal treatment.
Welding
904L can be successfully welded by all standard methods. Care needs to be taken as this grade solidifies fully austenitic, so is susceptible to hot cracking, particularly in constrained weldments. No pre-heat should be used and in most cases post weld heat treatment is also not required. AS 1554.6 pre-qualifies Grade 904L rods and electrodes for welding of 904L.
Fabrication
904L is a high purity, low sulphur grade, and as such will not machine well. Despite this the grade can be machined using standard techniques.
Bending to a small radius is readily carried out. In most cases this is performed cold. Subsequent annealing is generally not required, although it should be considered if the fabrication is to be used in an environment where severe stress corrosion cracking conditions are anticipated.
