Product Description
904L Stainless Steel Strip Overview
Grade 904L is a superaustenitic stainless steel engineered for moderate to high corrosion resistance across diverse industrial environments. With its optimized composition of 25% nickel and 4.5% molybdenum, this alloy delivers superior performance in corrosive applications.
Chemical Composition
| Grade | C | Mn | Si | P | S | Cr | Mo | Ni | Cu |
|---|---|---|---|---|---|---|---|---|---|
| 904L | ≤0.02 | ≤2 | ≤1 | ≤0.045 | ≤0.035 | 19-23 | 4-5 | 23-28 | 1-2 |
Performance Advantages
This high-purity steel offers excellent chloride stress corrosion cracking resistance, with pitting and general corrosion resistance superior to 316L and 317L molybdenum-enhanced stainless steels. Originally developed for dilute sulfuric acid environments, it also provides strong resistance to hot phosphoric acid and most organic acids.
Alternative Material Options
| Grade | Selection Criteria |
|---|---|
| 316L | Lower cost alternative with reduced corrosion resistance |
| 6Mo | Enhanced pitting and crevice corrosion resistance required |
| 2205 | Similar corrosion resistance with higher mechanical strength and lower cost (unsuitable above 300°C) |
| Super Duplex | Higher corrosion resistance and strength than 904L |
Fabrication Capabilities
Grade 904L stainless steel strips feature low sulfur content and can be machined using standard methods. They readily bend to small radii under cold conditions, with annealing recommended only for severe stress corrosion cracking applications.
Industrial Applications
- Electrostatic precipitator wiring systems
- Oil refinery components and equipment
- Seawater cooling devices and heat exchangers
- Gas scrubbing plant components
- Pulp and paper processing equipment
- Acetic, phosphoric and sulfuric acid processing plants
