AISI 904L Stainless Steel Coil is a high-alloy austenitic stainless steel known for its exceptional resistance to corrosion, particularly in acidic environments and chloride-containing media. This material is designed with a unique combination of elements to provide enhanced pitting and crevice corrosion resistance compared to standard grades like 316L.

Composition:

The typical chemical composition of 904L Stainless Steel includes:

- Chromium (Cr): Approximately 20% to 23%, which provides basic corrosion resistance.

- Nickel (Ni): A significant amount ranging from 23% to 28%, contributing to its excellent formability, ductility, and overall corrosion resistance.

- Molybdenum (Mo): Around 4% to 5%, enhancing the resistance against localized corrosion such as pitting and crevice corrosion.

- Copper (Cu): Up to 1%, added to improve resistance against sulfuric acid and other reducing acids.

- Titanium (Ti) and Nitrogen (N): Trace amounts are present to stabilize the structure and further enhance corrosion resistance by preventing intergranular corrosion.

Characteristics:

1. Corrosion Resistance: Offers superior resistance to a wide range of corrosive agents, including sulfuric acid, hydrochloric acid, and various chloride solutions.

2. Austenitic Structure: Provides good toughness, excellent formability, and weldability without the risk of cracking or embrittlement.

3. High Pitting Resistance Equivalent (PRE) Value: Due to its high chromium, nickel, and molybdenum content, it has a PRE value of more than 40, indicating its superior resistance to pitting corrosion.

4. Low Carbon Content: The low carbon content (<0.03%) reduces the risk of sensitization and improves resistance to intergranular corrosion after welding.

5. Heat Resistance: Withstands continuous service at temperatures up to around 400°C (752°F) while maintaining its mechanical properties.

Use:

1. Chemical Processing Industry: Components exposed to aggressive chemicals such as reactors, heat exchangers, tanks, and process piping systems.

2. Petrochemical Industry: Equipment handling sulfuric acid, alkylation units, and equipment in contact with sour crude oil.

3. Pharmaceutical and Food Processing: Equipment that requires high levels of sanitation and resistance to acidic cleaning agents.

4. Waste Treatment Plants: Components that come into contact with contaminated water and harsh chemicals.

5. Marine Applications: In areas where there is exposure to seawater and saline environments due to its resistance to chlorides.

In summary, AISI 904L Stainless Steel Coil is an ultra-high corrosion-resistant material specifically designed for challenging applications where conventional stainless steels may fail. Its unique blend of alloying elements makes it a premium choice for industries dealing with highly acidic or chloride-rich conditions, requiring both durability and long-term reliability.
