Certifications

Grade 904L stainless steel tubes are exceptionally resistant to warm seawater and chloride attack. The high nickel content in grade 904L's composition significantly enhances its resistance to stress corrosion cracking. Additionally, the integration of copper bolsters its resilience against sulfuric acid and various reducing agents in both aggressive and mild conditions.

The corrosion resistance of grade 904L stands between super austenitic grades (with 6% molybdenum) and the standard 316L austenitic grades. However, grade 904L is less resistant compared to grades 304L and 310L, which lack molybdenum. For optimal stress corrosion cracking resistance in critical environments, this steel grade requires solution treatment following cold working.

Heat Resistance

Grade 904L stainless steels exhibit good oxidation resistance. However, its structural stability diminishes at elevated temperatures, particularly beyond 400°C.

Heat Treatment

Grade 904L stainless steels can be solution heat-treated at temperatures ranging from 1090 to 1175°C, followed by rapid cooling. This thermal treatment is ideal for hardening these grades.

Welding

Welding grade 904L stainless steels can be executed using all conventional methods without the need for pre-heat or post-weld heat treatments. However, this grade may experience hot cracking in constrained weldments. For optimal results, grade 904L electrodes and rods should be used, adhering to AS 1554.6 standards.

Fabrication

Grade 904L stainless steel tubes are high-purity steels with low sulfur content. They are machinable using standard methods and can be easily bent to a small radius under cold conditions. While annealing is not usually necessary, it should be performed when fabrication involves severe stress corrosion cracking conditions.

Applications

Key applications of grade 904L stainless steel tubes include:

• Wiring in electrostatic precipitators
• Oil refinery components
• Seawater cooling devices
• Gas scrubbing plants
• Pulp and paper processing industries
• Acetic, phosphoric, and sulfuric acid processing plants
