ASTM SAE AISI 904L Stainless Steel (UNS N08904)

AISI 904L stainless steel (UNS N08904) is a high alloy austenitic stainless steel. Compared with 316L, SS904L has lower carbon (C) content, higher chromium (Cr) content, and approximatively twice the nickel (Ni) and molybdenum (Mo) content of 316L, which makes it have higher high temperature oxidation resistance, pitting resistance, and resistance to reducing acid (eg, sulfuric acid). Nitrogen (N) can reduce the rate of chromium carbide precipitation, thereby reducing the sensitivity of sensitization, it also improve the resistance to pitting and crevice corrosion caused by chlorides. Especially its addition of copper (Cu) makes it useful for all concentrations of sulfuric acid.

Possible Alternative Grades

The suitable alternatives to 904L stainless steels are tabulated below:

Table 5. Possible alternative grades to grade 904L stainless steels

Grade	Reasons for choosing grade 904L
316L	A lower cost alternative, but with much lower corrosion resistance.
6Mo	A higher resistance to pitting and crevice corrosion 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.

Applications

Some of the major applications of grade 904L stainless steels include:

Wiring in electrostatic precipitators
Oil refinery components
Seawater cooling devices
Gas scrubbing plants
Pulp and paper processing industries
Acetic, phosphoric and sulphuric acid processing plants
