Company Profile

All 904L type stainless steel supplied by Daxun Alloys adheres to premium manufacturing standards such as ASTM and EN. This superior stainless steel is non-magnetic under all conditions and boasts exceptional formability and welding properties. Thanks to its austenitic structure, it remains incredibly robust, even at cryogenic temperatures. The high chromium content fosters and sustains a passive film that shields the material from corrosive environments. In comparison to other molybdenum-containing stainless steels like 316L and 317L, 904L exhibits superior resistance to ferrite and sigma phase precipitation during cooling and welding. The low carbon content mitigates the risk of intergranular corrosion during these processes. With a maximum service temperature of 450°C, our 904L pipe stock is classified as ASTM A312 UNS N08904, SB 677 UNS N08904, and Werkstoff No. 1.4539.

Certifications

Grade 904L stainless steels tubes exhibit exceptional resistance to warm seawater and chloride attack. This grade's high resistance to stress corrosion cracking is attributed to its significant nickel content. Additionally, the incorporation of copper enhances its resistance to sulphuric acid and other reducing agents under both aggressive and 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 than grades 304L and 310L, which lack molybdenum. Solution treatment after cold working is required to maximize stress corrosion cracking resistance in critical environments.

Heat Resistance

Grade 904L stainless steels provide good oxidation resistance. However, structural stability diminishes at elevated temperatures, especially above 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 suitable for hardening these grades.

Welding

Welding of grade 904L stainless steels can be performed using all conventional methods. Pre-heat and post-weld heat treatments are not necessary. However, this grade can be prone to hot cracking in constrained weldments. Grade 904L electrodes and rods should be used for welding these steels according to AS 1554.6.

Fabrication

Grade 904L stainless steel tubes are high-purity steels with low *** content, suitable for machining by all standard methods. They can be easily bent to a small radius in cold conditions. While subsequent annealing is generally not required, it should be performed when fabrication occurs under severe stress corrosion cracking conditions.

Applications

The major 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 sulphuric acid processing plants
