Product Description

Overview
904L stainless steel is a super-austenitic stainless steel renowned for its exceptional corrosion resistance. Its high content of nickel, chromium, molybdenum, and copper provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in environments with high concentrations of sulfuric acid, phosphoric acid, and chlorides, such as seawater. It is primarily used in demanding environments such as the chemical, petrochemical, pharmaceutical, and marine engineering industries.

Key Features
The outstanding feature of 904L stainless steel lies in its high alloy content, providing exceptional resistance:
✓ Extremely Corrosion Resistance: High Ni, Cr, Mo, and Cu content ensures excellent performance in harsh media.
✓ Excellent Acid Resistance: Unmatched resistance against strong reducing acids like sulfuric and phosphoric acids.
✓ Localized Corrosion Resistance: High resistance to pitting and stress corrosion cracking (SCC) in high-chloride environments.
✓ Low Carbon Content: The "L" designation signifies low carbon, enhancing weldability and minimizing intergranular corrosion.
✓ Non-Magnetic: Maintains non-magnetic properties in all conditions.
✓ Good Formability: Offers the ductility and toughness characteristic of austenitic steel.

Frequently Asked Questions
What is 904L stainless steel?
904L is a high-alloy super-austenitic stainless steel known for its exceptional resistance to strong reducing acids and chloride-induced corrosion.
Why does 904L have better corrosion resistance than 316L?
904L contains higher levels of nickel and chromium, plus the addition of copper, which provides superior protection in sulfuric acid and high-chloride environments where 316L might fail.
Is 904L stainless steel magnetic?
No, 904L is a fully austenitic grade and remains non-magnetic in all conditions, including after welding or cold working.
What does the "L" in 904L stand for?
The "L" stands for "Low Carbon." This lower carbon content improves weldability and prevents intergranular corrosion by reducing carbide precipitation during the welding process.
In which industries is 904L commonly used?
It is widely used in chemical processing, oil and gas refining, pharmaceutical production, and marine engineering, especially for handling sulfuric and phosphoric acids.
What surface finishes are available for 904L plates?
Common finishes include 2B (cold rolled), No.1 (hot rolled), BA (bright annealed), mirror polish (8K), and various brushed or satin finishes.
