Product Parameters

Key Properties

The following sections describe the properties of flat rolled products in ASTM B625. The specifications may not be identical for other products such as bar, tube and pipe.

Composition

The table below provides the compositional ranges of grade 904L stainless steels:

Grade		C	Mn	Si	P	S	Cr	Mo	Ni	Cu
904L	min. max.	- 0.02	- 2	- 1	- 0.045	- 0.035	19 23	4 5	23 28	1 2

Mechanical Properties

The typical mechanical properties of grade 904L stainless steels are given in the table below:

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	36	70-90 typical	150

Corrosion Resistance

Grade 904L stainless steels have excellent resistance to warm seawater and chloride attack. The high resistance of grade 904L against stress corrosion cracking is due to the presence of high amounts of nickel in its composition. Moreover, the addition of copper to these grades develops resistance to sulphuric acid and other reducing agents in both aggressive and mild conditions.
The corrosion resistance of grade 904L is intermediate between super austenitic grades, with 6% molybdenum content, and standard 316L austenitic grades. Grade 904L is less resistant to nitric acid than grades 304L and 310L, which are free of molybdenum. This steel grade needs to be solution treated following cold working, to achieve maximum stress corrosion cracking resistance under critical environments.

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
