904L Super Austenitic Pipe and Tubing ASTM A312 / A358 Stainless Steel 904L Pipe Supplier, 904L Stainless Steel Seamless Pipe. Contact Us for ASME SA312 904L Stainless Steel Pipe.

904 alloy (N08904) stainless steel is a premium high-alloy austenitic product designed to withstand severe corrosion, boasting exceptional resistance.
904L stainless steel is a non-stabilized austenitic stainless steel with a low carbon content. This high-alloy stainless steel is enhanced with copper, boosting its resistance to strong reducing acids such as sulfuric acid. It is also highly resistant to stress corrosion, cracking, and crevice corrosion. Non-magnetic, 904L stainless steel offers outstanding formability, toughness, and welding capabilities, with a high concentration of costly elements like molybdenum and nickel.
904L grade stainless steel exhibits excellent resistance to hot seawater and chloride attack. The high nickel content significantly enhances stress corrosion cracking resistance. The addition of copper further improves resistance to sulfuric acid and other reducing agents in both corrosive and mild environments. The corrosion resistance of 904L grade steel is intermediate between super austenitic steels with 6% molybdenum and standard 316L austenitic steel. For optimal resistance to stress corrosion cracking in sensitive settings, this grade should undergo solution treatment following cold working.

Company Profile

Every piece of 904L stainless steel provided by Jiangsu Daxun Alloy Co., Ltd. is crafted to meet critical manufacturing standards like ASTM and EN. This non-magnetic stainless steel boasts exceptional formability and welding capabilities. Its robust austenitic structure ensures durability even at cryogenic temperatures. The high chromium content creates a passive film, protecting the steel from corrosive environments. Unlike other molybdenum-containing stainless steels such as 316L and 317L, 904L is more resilient against ferrite and sigma phase precipitation during cooling and welding. The low carbon composition further prevents intergranular corrosion during these processes. With a maximum service temperature of 450°C, our 904L pipe stock is thoroughly tested to meet industry benchmarks such as ASTM A312 UNS N08904, SB 677 UNS N08904, and Werkstoff No. 1.4539. Choose from a range of top-quality manufacturers and products, including 904L SS Seamless Pipe, ASTM B677 TP 904L SS Seamless Pipe, ASTM B674 TP 904L SS Pipe, SS 904L Welded Pipe, and more.

Certifications

Grade 904L stainless steels tubes exhibit outstanding resistance to warm seawater and chloride attacks. This exceptional durability against stress corrosion cracking is attributed to the significant nickel content in its composition. Furthermore, the inclusion of copper enhances its resistance to sulfuric acid and other reducing agents under both aggressive and mild conditions.

The corrosion resistance of grade 904L is intermediate between that of super austenitic grades with 6% molybdenum and standard 316L austenitic grades. Although less resistant than 304L and 310L grades, which are molybdenum-free, it excels in demanding environments. For optimum stress corrosion cracking resistance in critical environments, a solution treatment following cold working is essential.

Heat Resistance

Grade 904L stainless steels offer commendable oxidation resistance. Despite this, its structural stability diminishes at elevated temperatures, particularly above 400°C.

Heat Treatment

Grade 904L stainless steels can be effectively solution heat-treated between 1090 and 1175°C, followed by rapid cooling. This thermal treatment is ideal for hardening these grades.

Welding

Grade 904L stainless steels can be welded using all standard methods, without needing pre-heat or post-weld heat treatments. However, hot cracking can occur in constrained weldments. For optimal results, use grade 904L electrodes and rods compliant with AS 1554.6.

Fabrication

Grade 904L stainless steels tubes are characterized by high purity and low sulfur content, making them suitable for machining with standard methods. They can be easily bent to small radii under cold conditions. While subsequent annealing is generally unnecessary, it is recommended when the fabrication is performed under severe stress corrosion cracking conditions.

Applications

Some of the 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
