Hot Rolled UNS N08904 DIN1.4539 X1NiCrMoCu25-20-5 Stainless Steel Plate 10MM SS 904L Plate
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.
Datasheet and Specification
The following data sheet summarizes the chemical composition, properties, heat treatment and equivalent
grade of 904L stainless steel (SS904L).
Chemical Composition
The following data sheet gives SS 904L stainless steel chemical composition.
| | | | Chemical Composition, % |
| ASTM | UNS | Type | C, ≤ | Si, ≤ | Mn, ≤ | P, ≤ | S, ≤ | Cr | Ni | Mo | N, ≤ | Cu | Notes (Product) |
| ASTM A276/A276M | UNS S08904 | 904L | 0.02 | 1.00 | 2.00 | 0.045 | 0.030 | 19.0-23.0 | 23.0-28.0 | 4.0-5.0 | 0.10 | 1.0-2.0 | Bars and Shapes |
| ASTM A240/A240M | Plate, Sheet, and Strip |
Mechanical Properties
The following table lists 904L stainless steel (SS904L) mechanical properties such as yield strength,
tensile strength, elongation and hardness.
| | | AISI ASTM 904L Steel Mechanical Properties |
| ASTM | AISI Type | Tensile Strength, MPa (ksi), ≥ | 0.2% Yield Strength, MPa (ksi), ≥ | Elongation in 50 mm (2 in.), %, ≥ | Rockwell Hardness (HRBW), ≤ | Product forms | Conditions |
| ASTM A276/A276M | 904L (UNS N08904) | 490 (71) | 220 (31) | 35 | – | Bars and Shapes | Annealed, Hot-finished or cold-finished |
| ASTM A240/A240M | 490 (71) | 220 (31) | 35 | 90 | Plate, Sheet, and Strip | |
Heat Treatment
Annealing: The recommended annealing temperatures for 904L wrought steel is 1095 °C (2000 °F).
Corrosion
Type 304 stainless steel can handle mild foods and vegetables, but sauces and pickle liquors are more corrosive
and can even cause pitting corrosion on type 316 stainless steel. In order to improve pitting resistance,
high alloy 904L stainless steel (SS904L) should be considered.
Applications
904L stainless steel (SS904L) is used in petroleum, chemical, fertilizer, marine development towers, tanks,
pipes and tubes and heat exchangers.
SS 904L Equivalent Grade
The datasheet below summarizes 904L stainless steel equivalent grade such as European EN
(German DIN EN, British BS EN, French NF EN…), Chinese GB, ISO, Japanese JIS standard.
| AISI 904L equivalent material |
| US | European Union | ISO | Japan | China |
| Standard | Type | Standard | Grade (Steel Number) | Standard | ISO Name (ISO Number) | Standard | Grade | Standard |
| AISI SAE; ASTM | 904L (UNS N08904) | EN 10088-2; EN 10088-3 | X1NiCrMoCu25-20-5 (1.4539) | ISO 15510 | X1NiCrMoCu25-20-5 (4539-089-04-I) | JIS G4303 | SUS 890L | GB/T 20878; GB/T 4237; GB/T 3280 |
