We could produce 904L forging parts,904L forged rings, 904L Rolled Rings,904L forging flanges, 904L forging round bars, 904L forged disks, 904L forging bushings,904L forging discs,904L forged tubes, 904L forging sleeves,904L forging tube sheets, 904L forging shafts,904L forging pipes as per the requirement of the client
904L is a austenitic stainless steel alloy designed for a middles to high level of corrosion resistance.

We could delivery 904L forging material as per the standard of ASTM A-182

904L will be melted by AOD refining or vacuum induction melting. Vacuum arc or electroslag remelting procedure

904L should be annealed (solution treated) between 2000 and 2100°F (1095 and 1150°C) and quickly cooled.

The Chemical Composition of 904L is as follows:

C ≤ %	Si ≤ %	Mn ≤ %	P ≤ %	S ≤ %	Cr %	Mo %	Ni %	V
0,02	0,70	2,0	0,030	0,010	19,0-21,0	4,0-5,0	24,0-26,0
Nb	Ti	Al	Co	Cu %	N ≤ %	Fe
				1,20-2,00	0,15

The mechanical property of 904L is as follows:

Tensile Strength	Min 88KSI	Min 605MPA
Yield Strength	Min 39KSI	MIN 270MPA
Elongation	Min 50%

904L 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.

Due to special mechanical properties of 904L forging parts, there are many wide uses as followings:

904L seamless rolled ring and  904L forging shafts that is used in the ulphuric, phosphoric and acetic acids. petrolchemical industry, artificial fertalizers, food processing and pharmaceutical indistries, seawater desalinization plants

904L forged shafts,904Lforging pipes, 904L forged tubes ,forged tube sheets, forged flanges that are used in marine – seawater pumps, gate valves for seawater ballast systems on tankers, high-pressure (microbial) deep-sea sampler and incubation chambers and underwater robotic arms.

904L forging shafts,904L forging flanges ,904L forged rings,904L forging pipes that is used in offshore, sea water technology, chemical industry, good stability against reducing acids of medium strength like sulphuric acid and phosphoric acid and various chloric media, refinery, paper industry, pulp industry

904L open die forging parts,forging pieces,forging nozzles forged crankshaft that is used in Oil & Gas Production – oil field production and down-hole equipment

904L forged valve stems, forged valve parts, forged valve seat ring,forged valve blocks,forged bodies that are used in Pin and hanger expansion joints for bridges - better corrosion, galling-resistance, low temperature toughness, & high charpy values at sub-zero temps compared to the A36 and A588 carbon steels commonly used.
