UNS N08904 is a austenitic stainless steel alloy designed for a middles to high level of corrosion resistance.
We could delivery UNS N08904 forging material as per the standard of ASTM A-182
UNS N08904 will be melted by AOD refining or vacuum induction melting. Vacuum arc or electroslag remelting procedure
UNS N08904 should be annealed (solution treated) between 2000 and 2100°F (1095 and 1150°C) and quickly cooled.
The Chemical Composition of UNS N08904 is as follows:

Carbon		0.02 max
Chromium		19 - 23

The mechanical property of UNS N08904 is as follows:

Grade	Tensile Strength (MPa) min	Yield Strength 0.2% Proof (MPa) min	Elongation (% in 50mm) min	Hardness
				Rockwell B (HR B)	Brinell (HB)
904L	490	220	35	70-90 typical

UNS N08904 Possesses a very good reistance to sulphuric acid of any concentration up to about 60° C, as well as to phosphoric acid and organic acids.Excellent reistance to stress corrosion cracking, and pitting and crevice corrosion in media containing chloride ions.For optimium resistance, surfaces should be pickled.
