904 alloy (N08904) stainless steel is a high-alloy austenitic product renowned for its ability to endure harsh corrosion. It possesses exceptional corrosion resistance, making it ideal for challenging environments.
904L stainless steel is a non-stabilized austenitic stainless steel with a low carbon content. This high-alloy steel incorporates copper, enhancing its resistance to strong reducing acids such as sulfuric acid. Additionally, it resists stress corrosion, cracking, and crevice corrosion. 904L stainless steel is non-magnetic and boasts remarkable formability, toughness, and welding capabilities. The 904L grade contains significant amounts of costly elements like molybdenum and nickel, contributing to its superior properties.
904L grade stainless steel demonstrates exceptional resistance to hot seawater and chloride attack. Thanks to its high nickel content, this grade excels in resisting stress corrosion cracking. The addition of copper improves resistance to sulfuric acid and other reducing agents in both corrosive and mild environments. The corrosion resistance of 904L grade steel is superior to standard 316L austenitic steel and falls between super austenitic steels containing 6% molybdenum. To maximize resistance to stress corrosion cracking in sensitive settings, this grade requires solution treatment post-cold working.

Certifications

Grade 904L stainless steel tubes provide extraordinary resistance to warm seawater and chloride corrosion. Their superior stress corrosion cracking resistance is attributed to the high nickel content. Additionally, the incorporation of copper enhances resistance to sulfuric acid and various reducing agents, whether in aggressive or mild conditions.

The corrosion resistance of grade 904L sits between super austenitic grades with 6% molybdenum and standard 316L austenitic grades. It is less resistant compared to 304L and 310L grades, which are molybdenum-free. For optimal stress corrosion cracking resistance in critical environments, solution treatment is required after cold working.

Heat Resistance

Grade 904L stainless steel demonstrates good oxidation resistance. However, its structural stability tends to degrade at high temperatures, especially above 400°C.

Heat Treatment

Grade 904L stainless steel can be solution heat-treated at temperatures ranging from 1090 to 1175°C, followed by rapid cooling. This thermal treatment effectively hardens the material.

Welding

Grade 904L stainless steel can be welded using all conventional methods without the need for pre-heat or post-weld heat treatments. However, it is susceptible to hot cracking in constrained weldments. Use grade 904L electrodes and rods as specified by AS 1554.6 for best results.

Fabrication

Grade 904L stainless steel tubes are composed of high-purity steel with low sulfur content, allowing for easy machining using standard methods. They can be bent to a small radius under cold conditions. While subsequent annealing isn't usually required, it should be performed if the fabrication involves severe stress corrosion cracking conditions.

Applications

Major applications of grade 904L stainless steel tubes include:

• Wiring in electrostatic precipitators
• Components in oil refineries
• Seawater cooling devices
• Gas scrubbing plants
• Pulp and paper processing industries
• Processing plants for acetic, phosphoric, and sulfuric acids
