This blog aims to offer a complete understanding of Stainless Steel 904L’s properties, applications, and benefits, while showcasing why Mcneil Instrument is your best choice for this advanced alloy.
Decoding the Superior Corrosion Resistance of Stainless Steel 904L
A. Understanding the “Super Authenticate” Difference
Unlike standard grades like 304 or 316, 904L stainless steel features:
- High levels of chromium (19-23%)
- Nickel (23-28%)
- Molybdenum (4-5%)
- Copper (1-2%)
This enhanced chemistry ensures remarkable performance in aggressive and corrosive environments.
B. Key Benefits of 904L Composition
- Pitting & crevice corrosion resistance in chloride-rich areas.
- Superior resistance to sulfuric, phosphoric & acetic acids.
- Stress corrosion cracking prevention.
- Outstanding general corrosion resistance.
